EMBODIMENTS

FIG. 1 is a structural block diagram of a printing system according to an embodiment of the present invention.

As shown in FIG. 1, the printing system 100 includes a handheld printer 101 and a user terminal 102.

Here, the handheld printer 101 is a portable printer carried by the user. The user can perform sliding print at different places on a print medium, thereby conveniently printing the print content to be printed at any position of the print medium. The print medium may be paper, wall, desktop, cloth surface, and the like. The user terminal 102 is a computer, a smart phone, and the like operated by the user, and the computer and smart phone have its own system platforms, such as Windows, iOS, Android, and the like.

In the present embodiment, the handheld printer 101 may directly perform bidirectional communication with the user terminal 102 by Bluetooth, a wireless network, or a USB data cable without installing a printer driver. When the connection between the handheld printer 101 and the user terminal 102 is initially established, the user terminal 102 obtains device identification information of the handheld printer 101 based on a corresponding communication protocol, and establishes bidirectional data communication with the handheld printer 101 if it is determined that the device identification information meets a predetermined determination condition. The bidirectional data communication allows the user terminal 102 to send data to the handheld printer 101, query status, or set parameters, and allows the handheld printer 101 to actively feedback status information (such as printing status, battery power, and the like) to the user terminal 102.

In particular, when the handheld printer 101 and the user terminal 102 are communicably connected via a USB data line, the general system platform sets the access type of the handheld printer 101 to Usbprint.sys by default. In this case, USB bidirectional communication (USB Control transmission) cannot be performed between the user terminal 102 and the handheld printer 101. Accordingly, in the present embodiment, the user terminal 102 may switch the access type of the handheld printer 101 to WinUSB (the switch may be performed by OpenSource (liwdi)), if it is determined that the device identification information of the handheld printer 101 meets the predetermined determination conditions. In this way, it is capable of establishing the above bidirectional data communication via a USB data line.

In the present embodiment, as the above predetermined determination condition, for example, it may be determined whether the device identification information is the identification information of the corresponding handheld printer. In this way, it is capable of ensuring that the connected object is the handheld printer. The determination condition may also be set and adjusted according to actual needs. For example, it may be determined whether the device identification information corresponds to a certain type of handheld printer.

FIG. 2 is a structural block diagram of a handheld printer according to the embodiment of the present invention.

As shown in FIG. 2, the handheld printer 101 includes an inkjet printing unit 11, a sensing unit 12, an acquisition control unit 13, a printer-side communication unit 14, and a printer-side control unit 15.

Here, the printer-side communication unit performs data communication between the handheld printer 101 or the various components of the handheld printer 101 and the user terminal 102. The printer-side control unit 15 stores a computer program for controlling operations of each component of the handheld printer 101.

The inkjet printing unit performs inkjet printing at a predetermined inkjet width in one or more sliding directions when performing the sliding print.

In the present embodiment, the inkjet printing unit 11 includes an inkjet array 11a formed by a plurality of inkjet heads arranged on the handheld printer 101. As shown in FIG. 3, the inkjet array 11a ejects ink under the control of the acquisition control unit 13 thereby printing on the print medium, when the user presses a surface of the handheld printer 101, on which the inkjet printing unit 11 is provided, on the print medium while sliding the handheld printer 101 on a printing region 11c in the sliding direction 11b (the printed text is “red yellow blue green indigo blue purple”). Here, the length 11d of the inkjet array 11a is the maximum allowable inkjet width during inkjet printing.

The sensing unit 12 detects whether the surface of the handheld printer 101 on which the inkjet printing unit 11 is provided is pressed onto the print medium by the user.

Furthermore, in the present embodiment, the sensing unit 12 may also detect a sliding distance as the user slides the handheld printer 101 on the printing medium while performing the sliding print.

The acquisition control unit 13 acquires the bitmap format instructions, the print content mode, and the sliding print content, and controls the inkjet printing unit 11 and the sensing unit 12 to perform printing processing based on the read data, when the printer-side communication unit 14 receives the sliding print content, the corresponding bitmap format instructions, and print content mode sent by the user terminal 102.

In the present embodiment, the bitmap format instruction includes at least a start-end instruction, and processing sequence information corresponding to the bitmap. The print content mode includes at least the sliding direction of the sliding print motion. The acquisition control unit first acquires the bitmap format instruction and the print content mode, and controls the sensing unit 12 based on the start-end instruction to detect whether the handheld printer 101 is pressed onto the print medium by the user while sliding on the print medium.

Furthermore, the acquisition control unit 13 acquires the current sliding print content based on the processing sequence information in the bitmap format instruction, and controls the inkjet printing unit 11 to print the current sliding print content based on the sliding direction in the print content mode, if the sensing unit 12 detects that the handheld printer 101 is pressed onto the print medium by the user while sliding on the print medium. Furthermore, the acquisition control unit 13 controls the inkjet printing unit 11 to stop printing to have the user complete the current sliding print motion, if the sensing unit 12 detects that the handheld printer 101 is removed from the print medium.

In the present embodiment, regardless of whether the inkjet printing unit 11 has completed the current sliding print content, once the sensing unit detects that the handheld printer 101 is removed from the print medium, the acquisition control unit 13 will control the inkjet printing unit 11 to stop printing, and confirm that the current sliding print has been completed.

At the same time, the acquisition control unit 13 controls the printer-side communication unit to send a sliding print completion message corresponding to the current sliding print content to the user terminal 102, if the current sliding print motion is completed.

In addition, in the present embodiment, when the user slides the handheld printer 101, the acquisition control unit 13 controls the inkjet printing unit 11 in real time based on the sliding distance detected by the sensing unit 12 and the width of the inkjet array 11a, thereby enabling the user to perform inkjet printing during the sliding process.

In the present embodiment, as shown in FIG. 7, a length 24b(2) of the division image 24b(1) does not exceed the inkjet width ejection (that is, does not exceed the length 11d of the inkjet array 11a).

The sliding number determining unit 24c determines the number of the sliding print motions. In the present embodiment, if the print content is the text type, the sliding number determining unit 24c determines the number of sliding print motions based on the number of lines of the text information (for example, the number of line feed marks). If the print content is the graphic code type, the sliding number determining unit 24c determines the number of sliding print motions based on the number of graphic codes, that is, each graphic code corresponds to one sliding print motion. If the print content is the template type, the sliding number determining unit 24c determines the number of sliding print based on the information input in respective content input sections by the user, that is, each print content input in the content input section corresponds to one sliding print motion.

The bitmap generating unit 24d sequentially generates the respective bitmaps based on the number of sliding print motions and the print content. In the present embodiment, each bitmap corresponds to one sliding print motion.

The format instruction generation unit 24e generates bitmap format instructions corresponding to the respective bitmaps based on the input format of the print content.

In the present embodiment, the bitmap format instruction includes the processing sequence information (processing order) and a start-end code of each bitmap. For example, if the print content is the text type, the processing sequence information of the bitmap corresponding to each text line is determined based on the line break marks and line order (that is, the input Format) in text information (that is, the print content).

The color support information acquisition unit 25 acquires color support information of the handheld printer 101. The color support information is used to indicate whether the color supported by the handheld printer 101 is monochrome or color.

In the present embodiment, the color support information is included in the device identification information. For example, the device identification information may be in a form of “handheld printer, monochrome” or the like. The color support information acquisition unit 25 searches the device identification information for keywords to acquires the color support information of the corresponding handheld printer 101.

The sliding print content conversion unit converts each pixel in each of the bitmaps into binary data, and forms the sliding print content corresponding to the respective sliding print motions.

FIG. 11 is a structural block diagram of a sliding print content conversion unit according to the embodiment of the present invention.

As shown in FIG. 11, the sliding print content conversion unit 26 includes a support color determining unit 26a, a color data generation unit 26b, a bitmap color determining unit 26c, and a monochrome data generation unit 26d.

Specifically, the color support determining unit 26a determines whether the handheld printer supports color printing based on the color support information.

If the support color determining unit 26a determines that the handheld printer supports color printing, the color data generation unit 26b converts each pixel in each of the bitmaps into corresponding CMYK data (that is, using a conventional conversion method for converting data from RGB or ARGB to CMYK) as the binary data.

If the support color determining unit 26a determines that the handheld printer does not support color printing, the bitmap color determining unit 26c determines whether the bitmap is a monochrome image.

If the bitmap is a monochrome image, the monochrome data generating unit 26d converts each pixel in the bitmaps into corresponding 8 bpp monochrome data as the binary data.

If the bitmap is not a monochrome image, the monochrome data generating unit 26d performs grayscale conversion on the bitmaps, and converts each pixel in each of the bitmaps after the grayscale conversion into respective 8 bpp monochrome data as the binary data using a dithering algorithm.

In the present embodiment, after the sliding print content conversion unit 26 performs the conversion to obtain the sliding print content, the user-side communication unit 28 sends the sliding print content, and the corresponding bitmap format instructions and the print content mode to the handheld printer 101. Here, the sliding print content is composed of binary data, and the bitmap format instructions and the print content modes adopt a PJL (Printer Job Language), which can be combined into RPCS-R data that can be directly recognized by the handheld printer 101.

The prompt image generation unit 27 generates the prompt image prompting at least one of a printing order of the bitmaps and the sliding directions, based on the bitmaps, and the corresponding bitmap format instructions and the print content mode, if the user-side communication unit 28 sends the sliding print content, and the corresponding bitmap format instructions and print content mode to the handheld printer 10. Furthermore, the prompt image generating unit 27 generates a new prompt image by highlighting the bitmap corresponding to the currently printed sliding print content in the prompt image based on the sliding print completion message, so that the input display unit 22 displays the new prompt image in the printing prompt screen, if the user-side communication unit 28 receives the sliding print completion message.

FIG. 12 is a flowchart of the operations of the printing system according to the embodiment of the present invention.

As shown in FIG. 12, when the user uses the printing system 100, the process of inputting the print content and performing the sliding print is as follows.

In step S1, the input display unit 22 displays the content mode selection screen such that the user selects a print content mode from among a plurality of print content modes. The process proceeds to step S2 after the user selects the print content mode.

In step S2, the input display unit 22 displays the print content input screen such that the user inputs the print content corresponding to the print content mode. The process proceeds to step S3 after the user confirms the input print content.

In step S3, the print content processing unit 24 determines the number of sliding print motions and sequentially generates the bitmaps corresponding to the respective sliding print motions based on the corresponding print content mode and the inkjet width, and generates the bitmap format instructions corresponding to the respective bitmaps based on the input format of the print content. Then process proceeds to step S4.

In step S4, the sliding print content conversion unit 26 converts each pixel in each bitmap into binary data, and forms the sliding print content corresponding to the respective sliding print motions. Then the process proceeds to step S5.

In step S5, the user-side communication unit 28 sends the sliding print content, and the corresponding bitmap format instructions and print content mode to the handheld printer 101. Then the process proceeds to step S6.

In step S6, the acquisition control unit 13 acquires the sliding print content, and the corresponding bitmap format instructions and print content mode received by the printer-side communication unit 14. Then the process proceeds to step S7.

In step S7, the acquisition control unit 13 controls the sensing unit 12 to detect whether the handheld printer 101 is pressed onto the print medium by the user while sliding on the print medium. If the sensing unit 12 detects that the handheld printer 101 is pressed, the process proceeds to step S8.

In step S8, the acquisition control unit 13 acquires the current sliding print content based on the processing sequence information in the bitmap format instruction, and controls the inkjet printing unit 11 to print the current sliding print content. If the sensing unit 12 detects that the handheld printer 101 is removed from the print medium, the process proceeds to step S9.

In step S9, the acquisition control unit 13 controls the inkjet printing unit 11 to stop printing to have the user complete the current sliding print motion, and controls the printer-side communication unit 14 to send a sliding print completion message to the user terminal 102. Then the process proceeds to step S10.

In step S10, the acquisition control unit determines whether all of the sliding print motions have been completed based on the bitmap format instructions. If it is determined that it has not been completed, the process proceeds to step S7, and if it is determined that it has been completed, the process is terminated.

<Effect of Embodiments>

The print content processing unit determines, the number of sliding print motions, and sequentially generates one or more bitmaps and bitmap format instructions corresponding to the respective sliding print motions, after the user inputs and confirms print content corresponding to a print content mode. The sliding print content conversion unit converts the bitmaps into sliding print content corresponding to the respective sliding print motions. Then, the user terminal sends the sliding print content to a handheld printer so that the handheld printer performs sliding print. Thus, the printing system can directly convert print content input by a user into information that can be recognized by the handheld printer, and can send the data to the handheld printer so that the handheld printer performs sliding print. It is unnecessary for users to install a printer driver when using the handheld printer, thereby facilitating the user to print using the handheld printer.
