The present disclosure relates to a printing apparatus capable of printing on both sides of a printing medium with a printing material such as ink or toner in a noncontact manner and a method of controlling the printing apparatus.
There is an adjustment process for improving the accuracy of a position in which a printing material is printed. For example, in a printing apparatus which ejects ink from a print head and performs printing, in order to improve print quality, a registration adjustment is performed for each kind of ink ejectable from the print head to increase the landing accuracy of each ink on a printing medium. Incidentally, the registration adjustment is a process of reading and analyzing a test pattern printed on a printing medium by the print head to improve the control of a position in which a printing material is printed. The registration adjustment for improvement in landing accuracy of ink is referred to herein as “head adjustment” as appropriate. In a printing apparatus capable of printing on both sides of a printing medium, a predetermined pattern is printed on both sides to perform the head adjustment.
Japanese Patent Laid-Open No. 2020-019241 discloses a technique wherein on the occurrence of an error caused by inappropriate execution of a head adjustment at the time of initial setup, the head adjustment is performed again in a different method according to the content of the error.
However, the technique disclosed in Japanese Patent Laid-Open No. 2020-019241 relates to a technique after the occurrence of an error. The head adjustment must be performed again on the occurrence of an error, which increases the amount of consumption of consumables such as ink and printing medium.
In the first aspect of the present invention, there is provided a printing apparatus including:
In the second aspect of the present invention, there is provided a printing apparatus including:
In the third aspect of the present invention, there is provided a method of controlling a printing apparatus performing printing on a printing medium with a printing material, the method including:
According to the present disclosure, the occurrence of an error in the head adjustment can be prohibited (or suppressed).
Further features of the present disclosure will become apparent from the following description of exemplary embodiments with reference to the attached drawings.
An example of embodiments of the printing apparatus and control method will be hereinafter described in detail with reference to the accompanying drawings. It should be noted that the following embodiments do not limit the present disclosure and not all combinations of features explained in the embodiments are necessarily essential for means for solving of the present disclosure. It should also be noted that positions, shapes, and the like of constituent elements described in the embodiments are merely shown as examples and do not intend to restrict the scope of the disclosure to these examples.
First, a printing apparatus according to a first embodiment will be described with reference to
The printing apparatus 10 comprises a printing portion 12 which ejects ink to and performs printing on a printing medium, a feeding portion 14 which feeds a printing medium to the printing portion 12, and a discharge portion 16 which discharges a printing medium printed in the printing portion 12. The printing apparatus 10 also comprises a display portion 18 capable of displaying various types of information and an operation portion 20 which enables operation according to the content displayed on the display portion 18. The printing apparatus 10 further comprises a reversing portion 22 which reverses a printing side of a printing medium printed in the printing portion 12 to switch a printing side facing the print head and a reading portion 24 capable of reading an image on a printing side of a printing medium. The printing apparatus 10 further comprises a control portion 26 which controls entire operation, a communication portion 28 connected to an external apparatus in a communicable manner, and a generation portion 30 which generates print (print) data printable in the printing apparatus from input image data. The printing apparatus 10 also comprises a detection portion 32 capable of detecting whether a printing medium undergoing processing such as printing has been removed.
More specifically, the printing portion 12 comprises a print head (not shown) capable of ejecting ink, which is a printing material, by an inkjet method and performing printing on a printing medium fed from the feeding portion 14. The printing portion 12 performs a print operation of ejecting ink while moving the print head in an X direction with respect to a printing medium fed to a printing start position by the feeding portion 14 based on print data. The print operation is followed by a conveying operation of conveying the printing medium by a predetermined amount in a Y direction. After that, the print operation is performed again. The printing apparatus 10 alternately repeats the print operation and the conveying operation and thereby prints a predetermined image on the printing medium. Incidentally, although the printing apparatus 10 is described as an inkjet printing apparatus in the present embodiment, the printing method in the printing portion 12 is not limited to the one explained above and various publicly-known techniques are applicable. For example, the printing method may be an electrophotographic method. In this case, the printing material is toner.
The feeding portion 14 is located upstream of the printing portion 12 in the +Y direction and comprises a feeding tray 14a to place a printing medium before printing. The feeding portion 14 feeds a printing medium placed on the feeding tray 14a to the printing start position for the printing portion 12. The discharge portion 16 is located downstream of the printing portion 12 in the +Y direction and comprises a discharge tray 16a to place a printing medium after printing. The discharge portion 16 is configured to discharge a printing medium printed by the printing portion 12 to the discharge tray 16a protruding externally from the printing apparatus 10.
The display portion 18 is constituted of, for example, a liquid crystal display device, and can display characters, figures, indexes (indicators), and the like. Incidentally, the display portion 18 is not limited to the liquid crystal display device and may be formed by the use of an LED or any of various publicly-known display devices. Examples of the information displayed on the display portion 18 include setting information in the printing apparatus 10 and ink-related information such as an ink remaining amount and a type of ink in an ink tank storing ink to be ejected from the print head. The display on the display portion 18 is controlled by the control portion 26. The operation portion 20 is constituted of a switch, hard key, and the like for a user to perform various input operations. The operation portion 20 may be formed by a touch panel together with the display portion 18.
The reversing portion 22 is located, for example, between the printing portion 12 and the feeding portion 14 in the Y direction. The reversing portion 22 reverses a printing side of a printing medium printed by the printing portion 12 and makes the other printing side of the printing medium printable by the printing portion 12. Incidentally, a printing side means a side of a printing medium to which ink is ejected from the print head of the printing portion 12.
The reading portion 24 is configured to read an image printed on a printing medium. More specifically, the reading portion 24 is provided on a carriage which moves the print head of the printing portion 12 in the X direction. The reading portion 24 performs a reading operation of reading a printed image on a printing medium while moving in the X direction via the carriage with respect to the printing medium conveyed to a reading start position. The reading operation is followed by a conveying operation of conveying the printing medium by a predetermined amount in the Y direction. After that, the reading operation is performed again. The printing apparatus 10 alternately repeats the reading operation and the conveying operation and thereby reads the printed image on the printing medium. Incidentally, the configuration of the reading portion 24 is not limited to the above one. For example, it is possible to apply a publicly-known reading technique such as a configuration in which a reading sensor is provided to extend in the X direction and a printed image on a printing medium is read by conveying the printing medium under the reading sensor.
The control portion 26 comprises a CPU 302, a ROM 304, a RAM 306, and an EEPROM 308. The CPU 302 is a central processing unit to control each constituent of the printing apparatus 10. The CPU 302 also performs various types of processing such as an analysis of an image read by the reading portion 24. The ROM 304 stores various program codes executed by the CPU 302. The RAM 306 functions as a temporal storage area such as a work area of the CPU 302. The EEPROM 308 is a nonvolatile memory storing, for example, information on a shipping destination of the printing apparatus 10 and language settings for display on the display portion 18.
The communication portion 28 is connectable to an external apparatus via a USB (Universal Serial Bus) or a network. That is, the communication portion 28 is connected to a USB or a network and communicates with an external apparatus. The generation portion 30 generates print data printable by the printing portion 12 from image data input from an external apparatus via the communication portion 28. Incidentally, the image data is not limited to an image that a user wants to print on a printing medium but includes, for example, nozzle check data designated by a user and pattern data on an adjustment pattern for a head adjustment. The detection portion 32 is a constituent to detect whether a printing medium undergoing printing (including waiting for ink drying) has been removed from the printing apparatus 10. Since a publicly-known technique can be used for a specific configuration of the detection portion 32, the detailed description thereof is omitted.
In the printing apparatus 10, the constituents described above are connected to each other via a bus 310 and can transmit/receive data to/from each other. Incidentally, although the printing apparatus which performs printing on a printing medium is described as an example in the present embodiment, the technique of the present embodiment is also applicable to various publicly-known apparatuses having the function of printing on both of front and back sides of a printing medium, such as a multifunction peripheral equipped with a scanner. Further, the head adjustment is automatically performed in the present embodiment but is not limited to this and may be semi-automatically performed as disclosed in Patent Literature 1.
The printing apparatus 10 is capable of single-sided printing, in which one side (front side) of a printing medium is printed, and double-sided printing, in which one side and the other side (back side) of a printing medium are printed.
In single-sided printing, a printing medium M is first placed on the feeding tray 14a of the feeding portion 14 (see
On the other hand, in double-sided printing, printing is performed on a front side of a printing medium M like the single-sided printing, but a part of the printing medium M is located on the discharge tray 16a and exposed to the outside of the apparatus during printing (see
In the printing apparatus 10, in the case of performing a head adjustment process, which is a process for adjusting a landing position of ink, a head adjustment pattern (adjustment process pattern) is first printed on a printing medium. Incidentally, the head adjustment pattern means a pattern for a registration adjustment and is hereinafter referred to as “adjustment pattern” as appropriate. The adjustment pattern printed on the printing medium is then read by the reading portion 24. After that, the control portion 26 analyzes the read information and obtains information for correcting a landing position of ink based on the analysis result. At the time of printing, the control portion 26 corrects the landing position of ink based on the information and performs control to eject ink from the print head. Incidentally, single-sided printing and double-sided printing are available for printing of the adjustment pattern for the head adjustment process; the printing apparatus 10 can perform both or either of single-sided printing and double-sided printing of the adjustment pattern. In double-sided adjustment pattern printing, adjustment patterns printed on the front and back sides of a printing medium may be either different from or identical to each other.
Since the printing apparatus 10 is capable of double-sided printing, there is a need to perform both a head adjustment for printing on a front side and a head adjustment for printing on a back side. More specifically, the printing portion 12 first prints an adjustment pattern on a front side of a printing medium fed from the feeding portion 14. After the printing of the adjustment pattern on the printing medium, the printing medium waits a predetermined time at a predetermined position for drying of ink ejected on the front side. The printing medium is then pulled back and conveyed to the reversing portion 22 and reversed by the reversing portion 22. After that, the printing portion 12 prints an adjustment pattern on the back side of the printing medium. After the printing, the printing medium waits a predetermined time at a predetermined position for drying of ink ejected on the back side.
Next, the printing medium is pulled back and conveyed to the reversing portion 22 and reversed by the reversing portion 22, and the reading portion 24 reads the adjustment pattern printed on the front side. After the reading of the adjustment pattern on the front side is finished, the printing medium is pulled back and conveyed to the reversing portion 22 and reversed by the reversing portion 22, and the reading portion 24 reads the adjustment pattern printed on the back side. After that, the control portion 26 analyzes the read adjustment patterns on the front and back sides and obtains information for correcting a landing position of ink based on the analysis. Incidentally, since various publicly-known techniques can be used to analyze the read adjustment patterns and obtain information for correcting a landing position of ink, the detailed description thereof is omitted.
As stated above, in the case of performing the head adjustment process, the adjustment pattern is printed on the front and back sides of the printing medium, but the printing medium with the front side printed waits for ink drying before the printing medium is reversed. At this time, the printing medium is exposed to the outside of the apparatus as shown in
Incidentally, also in single-sided printing of the adjustment pattern in the head adjustment process, the same problem arises in a case where a printing medium with its front side printed is exposed to the outside of the printing apparatus 10 to wait for drying and is then pulled back to read the adjustment pattern printed on the front side. Further, also in double-sided printing of the adjustment pattern in the head adjustment process, the same problem arises in a case where a printing medium with its back side printed is exposed to the outside of the printing apparatus 10 to wait for drying and is then pulled back to read the adjustment patterns printed on both the sides. Accordingly, the process described below is also applicable to the above cases, that is, cases where there is a need to prohibit (or suppress) a user from removing a printing medium in the execution of the process of exposing the printing medium subjected to a printing process to the outside of the printing apparatus 10 and then pulling the printing medium back to the printing apparatus 10.
Thus, in the present embodiment, identification information for prohibiting (or suppressing) a user from touching a printing medium is notified at the time of printing the adjustment pattern in order to prohibit (or suppress) a user from removing the printing medium during printing. More specifically, at the time of printing on a front side of a printing medium, an illustration or character string to prohibit (or suppress) touching the printing medium is printed on the printing medium, or an animation, guidance, character string, or message to prohibit (or suppress) touching the printing medium is displayed on the display portion 18.
In the present embodiment, the head adjustment process for adjusting a landing position of ink is performed at a predetermined time such as the time of initial setup after arrival or the time of print head replacement. In the head adjustment process, the adjustment pattern printing process for printing an adjustment pattern is performed for both sides of a printing medium, followed by reading of the adjustment patterns printed on both the sides of the printing medium. After that, the read adjustment patterns are analyzed by the control portion 26 to obtain information for correcting a landing position of ink. Since various publicly-known techniques can be used to read the adjustment patterns and analyze the read adjustment patterns, the detailed description thereof is omitted.
The adjustment pattern printing process for printing an adjustment pattern on both sides of a printing medium will be described below in detail.
If the adjustment pattern printing process is started, the CPU 302 first determines whether printing should be performed on the front side of the printing medium (S502). In S502, for example, it is determined whether the printing medium has been fed from the feeding portion 14 or reversed in the reversing portion 22. The determination is made, for example, based on the detection of the printing medium by sensors provided in the feeding portion 14 and the reversing portion 22. In this case, in S502, if the printing medium is fed from the feeding portion 14, it is determined that printing should be performed on the front side of the printing medium. If the printing medium is conveyed from the reversing portion 22, it is determined that printing should be performed on the back side, not the front side, of the printing medium. Incidentally, this determination method is just an example and various publicly-known techniques are applicable.
If it is determined in S502 that printing should be performed on the front side of the printing medium, the CPU 302 determines whether an adjustment pattern was printed without error (S504). As will be described later in detail, in the case of printing an adjustment pattern, the printing apparatus 10 detects an error upon removal of a printing medium undergoing printing, that is, removal of a printing medium from the printing apparatus 10 before the finish of printing of the adjustment pattern on both sides, and stores the error detection in the storage area. S504 determines whether the adjustment pattern was printed without the above error in the last printing process.
A storage area such as the EEPROM 308 stores, as error-related information, whether or not the adjustment pattern was printed without error. Accordingly, based on the error-related information stored in the storage area, it is determined in S504 whether or not the adjustment pattern was printed without error. That is, if the storage area stores information that the adjustment pattern was printed without error, it is determined in S504 that the adjustment pattern was printed without error. If the storage area stores information that the adjustment pattern was not printed without error, it is determined that the adjustment pattern was not printed without error. An initial value of the error-related information is that “the adjustment pattern was not printed without error.” Alternatively, the determination may be made based on whether error detection has been stored. The process advances to S508 if it is determined that error detection has been stored, and proceeds to S506 if it is determined that error detection has not been stored. That is, if a user removed a printing medium during the last printing of the adjustment process pattern, control is executed so as to perform printing to prohibit (or suppress) a user from removing a printing medium. If a user did not remove a printing medium during the last printing of the adjustment process pattern, control is executed so as not to perform printing to prohibit (or suppress) a user from removing a printing medium.
If it is determined in S504 that the adjustment pattern was printed without error, the adjustment pattern is printed on the front side of the printing medium based on print data on the adjustment pattern generated in the generation portion 30 (S506), and the process returns to S502. Incidentally, since any publicly-known adjustment pattern can be used as the adjustment pattern, the detailed illustration and description thereof are omitted herein. As described above, in the present embodiment, the CPU 302 functions as a printing control portion which controls the printing portion 12 and the like to print the adjustment pattern on the front side of the printing medium.
If it is determined in S504 that the adjustment pattern was not printed without error, the CPU 302 displays identification information for prohibiting (or suppressing) touching the printing medium on the display portion 18 (S508). The display of the identification information for prohibiting (or suppressing) touching the printing medium is, for example, an animation, guidance, or character string from which a user can easily recognize that the printing medium must not be touched (or must be suppressed from being touched).
The display of the identification information for prohibiting (or suppressing) touching the printing medium on the display portion 18 is started in S508 in the flowchart of
As described above, a period during which the identification information for prohibiting (or suppressing) touching the printing medium is displayed on the display portion 18 may be any period provided that it includes a time in which there is at least a need to prohibit (or suppress) a user from removing the printing medium. The time in which there is at least a need to prohibit (or suppress) a user from removing the printing medium is, for example, a time in which the printing medium is exposed to the outside of the printing apparatus 10 before being pulled back to the printing apparatus 10. In this manner, in the present embodiment, the CPU 302 functions as a notification portion which performs a notification process of displaying the identification information indicating the head adjustment process and the identification information for prohibiting (or suppressing) touching the printing medium on the display portion 18 and notifying a user of the identification information.
Returning to
On the printing medium, the prohibition (or suppression) image is located in a position exposed to the outside of the printing apparatus 10 and easily visible to a user during printing of the adjustment pattern on the front side and during waiting for ink drying after the printing on the front side. The prohibition (or suppression) image should be an illustration, icon, or character string from which a user can easily recognize that the printing medium must not be touched. For example, an image or icon to prohibit (or suppress) touching the printing medium may be printed on the printing medium together with the following identification information indicating the head adjustment process: “Adjustment is being performed to improve print quality. Do not extract the sheet.” Further, the prohibition (or suppression) image may have a color easy to attract a user's attention, a conspicuous color, or a color that enhances user recognition, such as red.
In S510, an image as shown in
Returning to
If it is determined in S514 that an error has occurred, the CPU 302 stops printing (S516) and finishes the adjustment pattern printing process. At this time, the display portion 18 may display a notification that an error has occurred or an instruction to fix an error. In S516, the error-related information stored in the storage area is updated to “the adjustment pattern was not printed without error.”
If it is determined in S514 that an error has not occurred, the CPU 302 determines whether the printing of the adjustment pattern has been finished (S518). If it is determined in S518 that the printing of the adjustment pattern has not been finished, the process returns to S514. If it is determined in S518 that the printing of the adjustment pattern has been finished, the error-related information stored in the storage area is updated to “the adjustment pattern was printed without error” (S520) and the adjustment pattern printing process is finished.
As described above, according to the present embodiment, a notification to prohibit (or suppress) touching a printing medium is made at the time of printing the adjustment pattern on the front side in the adjustment pattern printing process in the head adjustment process. More specifically, the prohibition (or suppression) image to prohibit (or suppress) touching the printing medium is additionally printed and the display to prohibit (or suppress) touching the printing medium is made on the display portion 18. This can prohibit (or suppress) the occurrence of an error which is caused by removal of the printing medium by a user in the adjustment pattern printing process and disables an appropriate head adjustment.
Incidentally, in the above embodiment, the notification to prohibit (or suppress) touching the printing medium is made in a case where the adjustment pattern is printed on the front side in the adjustment pattern printing process in the head adjustment process. On the other hand, in execution of normal double-sided printing, the CPU 302 executes control to display indication information (such as a character string or message) indicating that printing is being performed on the display portion 18 but does not execute control to notify prohibition (or suppression) of touching the printing medium. For example, in execution of normal double-sided printing, the CPU 302 displays a message “Printing is being performed” on the display portion 18 without displaying a character string or message to prohibit (or suppress) touching the printing medium. The CPU 302 also does not print on the printing medium an image or icon to prohibit (or suppress) touching the printing medium. Incidentally, the execution of normal double-sided printing means that a print job having a setting of double-sided printing of print data on a first side of a printing medium and a second side, which is the back side of the first side, is executed under user instructions.
Further, in the above embodiment, as the notification process for prohibiting (or suppressing) touching the printing medium, the prohibition (or suppression) image to prohibit (or suppress) touching the printing medium is additionally printed and the display to prohibit (or suppress) touching the printing medium is displayed on the display portion 18. However, at least one of the above printing and display processes may be executed as the notification process. That is, after the execution of S508 of
Further, in the present embodiment, if the adjustment pattern is printed without error, the next adjustment pattern printing process is performed without printing the prohibition (or suppression) image or making the display of prohibition (or suppression) of touching the printing medium. This enables prohibition (or suppression) of consumption of ink, printing medium, and power.
Next, a printing apparatus according to a second embodiment will be described with reference to
The second embodiment is different from the first embodiment described above in that in the adjustment pattern printing process in the head adjustment process, if the printing on the back side is finished without error, a user is allowed to select whether to make a notification to prohibit (or suppress) touching a printing medium.
In the present embodiment, as information related to a notification to prohibit (or suppress) touching a printing medium, the storage area such as the EEPROM 308 stores execution or non-execution of the notification. In the following description, “information related to a notification to prohibit (or suppress) touching a printing medium” is simply referred to as “notification-related information” as appropriate. An initial value of the notification-related information is that “a notification to prohibit (or suppress) touching a printing medium should be executed.” Based on the notification-related information, the CPU 302 determines whether to make a notification to prohibit (or suppress) touching a printing medium at the time of printing on the front side of the printing medium.
A description will be given of an adjustment pattern printing process executed in the present embodiment.
If the adjustment pattern printing process is started, it is first determined in S502 whether printing should be performed on the front side of the printing medium. If it is determined that printing should be performed on the front side of the printing medium, the CPU 302 determines whether to execute a notification to prohibit (or suppress) touching the printing medium (S802). In the present embodiment, the storage area such as the EEPROM 308 stores the notification-related information indicating whether to execute a notification to prohibit (or suppress) touching a printing medium. Accordingly, the determination is made in S802 based on the notification-related information. That is, if the execution of a notification to prohibit (or suppress) touching a printing medium is stored as the notification-related information, it is determined in S802 that a notification to prohibit (or suppress) touching the printing medium should be executed. If the non-execution of a notification to prohibit (or suppress) touching a printing medium is stored as the notification-related information, it is determined that a notification to prohibit (or suppress) touching the printing medium should not be executed.
If it is determined in S802 that a notification to prohibit (or suppress) touching the printing medium should not be executed, the process advances to S506, where the adjustment pattern is printed on the front side of the printing medium, and then returns to S502. If it is determined in S802 that a notification to prohibit (or suppress) touching the printing medium should be executed, the process advances to S508, where a display to prohibit (or suppress) touching the printing medium is made on the display portion 18. After that, in S510, the prohibition (or suppression) image is printed together with the adjustment pattern on the front side of the printing medium based on the additional print data and the process returns to S502.
On the other hand, it is determined in S502 that printing should be performed not on the front side of the printing medium, the adjustment pattern is printed on the back side of the printing medium in S512 and it is determined in S514 whether an error has occurred. If it is determined in S514 that an error has occurred, the CPU 302 stops printing (S804) and finishes the adjustment pattern printing process. At this time, the display portion 18 may display a notification that an error has occurred or a process to fix an error. In S804, the notification-related information stored in the storage area is updated to “a notification to prohibit (or suppress) touching a printing medium should be executed.”
If it is determined in S514 that an error has not occurred, it is determined in S518 whether the printing has been finished. If it is determined that the printing has not been finished, the process returns to S514. If it is determined in S518 that the printing has been finished, the CPU 302 prompts a user to select whether to execute a notification to prohibit (or suppress) touching a printing medium (S806). In S806, the display portion 18 displays a selection screen which prompts a user to select whether to execute a notification to prohibit (or suppress) touching a printing medium.
After that, the CPU 302 updates the notification-related information stored in the storage area based on the result of user selection on the selection screen 902 (S808) and finishes the adjustment pattern printing process. In S808, if a user selects the “YES” button 904 on the selection screen 902, the notification-related information in the storage area is updated to “a notification to prohibit (or suppress) touching a printing medium should be executed.” If a user selects the “NO” button 906 on the selection screen 902, the notification-related information in the storage area is updated to “a notification to prohibit (or suppress) touching a printing medium should not be executed.”
As described above, in the present embodiment, a notification to prohibit (or suppress) touching a printing medium is made at the time of printing the adjustment pattern on the front side in the adjustment pattern printing process in the head adjustment process like the first embodiment. Further, in the present embodiment, a notification to prohibit (or suppress) touching a printing medium is executed according to user selection. This produces the same advantageous result as that of the first embodiment.
Furthermore, since whether to execute a notification to prohibit (or suppress) touching a printing medium can be determined according to user selection, the occurrence of an error that disables an appropriate head adjustment can be suppressed even in a case where the printing apparatus 10 is shared among a plurality of users.
In the second embodiment, as the notification process for prohibiting (or suppressing) touching the printing medium, the printing process of printing the identification information to prohibit (or suppress) the touching and the display process of making a display to prohibit (or suppress) the touching on the display portion 18 are executed. However, at least either one of the printing process and the display process may be executed as the notification process. In this case, the selection screen which allows selecting whether to make a notification to prohibit (or suppress) touching the printing medium may be a screen which allows selecting execution of either one or both of the printing process and the display process. In S508 or S510 of
The embodiments described above may be modified as shown in (1) to (5) below.
(1) In the above embodiments, a notification to prohibit (or suppress) touching a printing medium is made at the time of printing the adjustment pattern on a front side in the case of printing the adjustment pattern on both sides of a printing medium, but is not limited to this. Predetermined patterns for various adjustments may be printed. Alternatively, for example, in the case of printing an image desired by a user on both sides of a printing medium, a notification to prohibit (or suppress) touching the printing medium may be made at the time of printing the desired image on the front side. In this case, the notification to prohibit (or suppress) touching the printing medium is limited to a display of an animation, guidance, or character string on the display portion 18 and a prohibition (or suppression) image is not printed. This will be described below in detail with reference to
If the printing process of
If it is determined in S502 that printing should be performed not on the front side of the printing medium, the CPU 302 prints a desired image on the back side of the printing medium based on print data generated by the generation portion 30 (S1004). The print data used in S1004 is print data on an image to be printed on the back side of the printing medium generated by the generation portion 30. After that, the CPU 302 determines whether the printing has been finished (S1006). If it is determined that the printing has been finished, the printing process is finished. If it is determined in S1006 that the printing has not been finished, the process returns to S502.
As described above, in the printing process of
(2) In the above embodiments, the prohibition (or suppression) image is additionally printed on the front side of the printing medium to prohibit (or suppress) a user from touching the printing medium, but is not limited to this. The prohibition (or suppression) image may be additionally printed also on the back side of the printing medium. This can prohibit (or suppress) a user from removing the printing medium, for example, at the time of waiting after the printing of the adjustment pattern on the back side, thereby prohibiting (or suppressing) the occurrence of an error with more reliability.
(3) In the above embodiments, a notification to prohibit (or suppress) touching a printing medium is made by printing an illustration and character string and displaying an animation, guidance, or character string, but is not limited to this. That is, it is only necessary to execute at least one of printing of an illustration, printing of a character string, display of an animation, display of a guidance, and display of a character string. It is also possible to provide a guidance through a speaker to prohibit (or suppress) removal of a printing medium.
(4) In the above embodiments, in a case where the adjustment pattern has been printed on a back side without error, if a user chooses not to make a notification to prohibit (or suppress) touching a printing medium, a notification to prohibit (or suppress) touching a printing medium is not made, but is not limited to this. That is, in the case of printing the adjustment pattern on both sides of a printing medium, a notification to prohibit (or suppress) touching a printing medium may be executed whenever the adjustment pattern is printed on a front side.
(5) Although not particularly described in the above embodiments, in the case of not making a notification to prohibit (or suppress) touching a printing medium, a display to prohibit (or suppress) touching a printing medium may be made on the display portion 18 without printing a prohibition (or suppression) image that is an image to prohibit (or suppress) touching a printing medium. Further, although not particularly described in the above embodiments, the printing apparatus 10 to which the above embodiments are applicable may be a printing apparatus without the display portion 18.
