JP-A-2014-118236 (Patent Literature 1) discloses an image forming system including an image forming apparatus that performs printing on a sheet and a post-processing apparatus that performs binding on a sheet bundle as post processing after the printing. This system controls, based on at least one kind of sheet information among a type, thickness, and basis weight of sheets included in the sheet bundle, whether to prohibit the binding. Depending on a printing system, other kinds of post processing such as punching and stapling are possible as the post processing other than the binding.
However, when a user desires to use different kinds of paper for a text and a cover, a print intended by the user sometimes cannot be obtained. For example, when the user intends to print the text using plain paper and print the cover using thick paper, the post processing by the post-processing apparatus cannot be performed on the cover. As a result, it is likely that a post-processed print intended by the user cannot be obtained.

The printing unit 2 includes a printing section 10, a scanner section 12, and a cassette housing section 14. The scanner section 12 is a mechanism for reading information of a document and is used when the printing apparatus 1 is used as a copy machine and when a scan result is transmitted to other apparatuses. However, the scanner section 12 can be omitted.
The printing section 10 includes a printing head 20. The printing head 20 is a head of an inkjet type and ejects ink to a printing medium P. As the printing medium P, usually, paper formed as a singled sheet is used. In the following explanation, the printing medium P is referred to as “paper P”.
The cassette housing section 14 includes a plurality of paper cassettes 51 to 54 that house paper P. A conveying path 15 on which the paper P is conveyed is formed in the printing section 10 and the cassette housing section 14. The conveying path 15 includes a paper feeding path 16, a discharging path 17, a reversing path 18, and a delivery path 19. In the conveying path 15, the paper P is conveyed from the paper cassettes 51 to 54 to right under the printing head 20 and further conveyed to the post-processing unit 3.
The post-processing unit 3 includes an intermediate unit 4 that conveys the paper P received from the printing unit 2 and an end unit 5 that collectively post-processes a necessary number of pieces of the paper P received from the intermediate unit 4. The post-processing unit 3 accumulates a plurality of pieces of the paper P printed by the printing section 10 in a post-processing tray 36 as a paper bundle Q and executes post processing on the paper bundle Q. The post processing can be selected out of a plurality of kinds of post processing including stapling, punching, saddle stapling, saddle folding, and shifting. The “stapling” is processing for binding a corner portion or a side portion of the paper bundle Q with staples. The “punching” is processing for opening a plurality of punch holes in the paper bundle Q. The “saddle stapling” is processing for aligning and stacking a cover and a text and binding the center of the cover and the text with staples to thereby finish the cover and the text like a booklet. The “saddle folding” is processing for folding paper in the center of the paper. The “shifting” is processing for shifting a paper discharge position for each of documents to make it easy to sort paper. The post-processing unit 3 may be configured to be capable of executing post processing other than these kinds of processing or may be configured to be capable of executing one kind of post processing.
The intermediate unit 4 conveys the paper P received from the printing unit 2 and passes the paper P to the end unit 5. In the intermediate unit 4, a conveying path M configured by a plurality of paths on which the paper P received from the printing unit 2 is conveyed is formed. In the conveying path M, the paper P is switched back on one of paths of two systems. The intermediate unit 4 may be omitted to directly convey the paper P from the printing unit 2 to the end unit 5.
The end unit 5 includes a medium discharging section 30 and a post-processing executing section 34 that performs post processing on the paper bundle Q including a plurality of pieces of paper P. The medium discharging section 30 and the post-processing executing section 34 are housed in a housing 31. The housing 31 includes an upper tray 32 and a discharge tray 38 on which the paper P is placed. In the housing 31, a conveying path K on which the paper P is conveyed from the intermediate unit 4 is formed. The paper P not post-processed by the post-processing executing section 34 is discharged to the upper tray 32. The paper P post-processed by the post-processing executing section 34 is discharged to the discharge tray 38.
The basic setting screen W1 includes a plurality of setting items including a paper feeding method, a paper size, and a paper type. In
When a user selects the “divide a paper feeding section for each type of paper” out of the options of the paper feeding method on the basic setting screen W1, a paper feeding setting screen W2 is displayed separately from the basic setting screen W1. The paper feeding setting screen W2 is a screen on which paper feeding setting for a cover/a text is performed. The paper feeding setting screen W2 includes a setting item for a front cover, a setting item for a text, and a setting item for a back cover. These setting items respectively include settings for paper feeding methods. The front cover and the back cover further include setting concerning whether to perform printing. Options of the paper feeding method for the front cover include, although a part of illustration is omitted, “automatic selection” and “paper cassette 1” to “paper cassette 4”. Options of the paper feeding method for the text include “follow the first paper” and “paper cassette 1” to “paper cassette 4”. The “first paper” means the front cover. Options of the paper feeding method for the back cover include, although a part of illustration is omitted, “follow the second paper” and “paper cassette 1” to “paper cassette 4”. The “second paper” means the text. The setting items for the back cover may be omitted from the paper feeding setting screen W2.
The user is capable of respectively setting the paper feeding method for the front cover, the text, and the back cover using the paper feeding setting screen W2. In this embodiment, it is assumed that paper cassettes different from each other are set as the paper feeding methods for the front cover and the text. Among the plurality of paper cassettes 51 to 54 of the printing apparatus 1, a paper cassette selected for paper for text on the paper feeding setting screen W2 is referred to as “first paper feeding section” and a paper cassette selected for paper for front cover on the paper feeding setting screen W2 is referred to as “second paper feeding section”. For example, the paper cassette 51 is selected as the “first paper feeding section” for the paper for text and the paper cassette 52 is selected as the “second paper feeding section” for the paper for front cover. A simple term “cover” means the front cover.
When the user selects “divide a paper feeding section for each type of paper” out of the options for the paper feeding method on the basic setting screen W1 as shown in
When execution of printing is instructed by a user of the computer 100 after printing conditions are set, the printing-output-data generating section 112 of the printer driver 110 creates printing output data according to the printing conditions. The printing output data is supplied from the computer 100 to the printing apparatus 1.
The printing output data POD includes a header and a body including dot data. The dot data is data representing presence or absence of formation of dots in pixels on the paper P and a dot size. The dot size means an ejection amount of ink. Since the dot size depends on surface characteristics of the paper P, the dot data is different in the plain paper, the super fine paper, and the matte paper. However, in the plain paper, the recycled paper, the thick paper 1 and the thick paper 2, and the special thick paper, since surface characteristics thereof are substantially the same, the dot data is the same.
The header of the printing output data POD includes paper type designation information PTS, paper feeding section designation information FES, and post-processing designation information FIS. The paper type designation information PTS is data for designating a paper type of paper used for printing. In
The paper-type setting section 221 of the printing apparatus 1 displays, on a not-shown operation panel of the printing apparatus 1, a screen for setting paper types of the paper P placed on the plurality of paper cassettes 51 to 54 of the printing apparatus 1. The paper-type setting section 221 sets, in the printing apparatus 1, a paper type designated by the user using the operation panel. In
The storing section 222 of the printing apparatus 1 stores a plurality of paper types for which the specific post processing by the post-processing unit 3 is possible. As explained above with reference to
In step S100, the user sets paper types of the paper feeding sections using the paper-type setting section 221 of the printing apparatus 1. The “paper feeding sections” mean the paper cassettes 51 to 54 of the printing apparatus 1. In
In step S110, the control section 22 of the printing apparatus 1 receives the printing output data POD. In step S120, the control section 22 determines whether paper feeding sections for a cover and a text are individually designated by the paper feeding section designation information FFS of the printing output data POD. When paper feeding section for a cover and a text are not individually designated, processing of the flowchart proceeds to step S160 and the control section 22 determines whether various settings designated by the printing output data POD and various settings designated in advance by the printing apparatus 1 contradict each other. When the settings do not contradict each other, the processing proceeds to step S150 and the control executing section 223 executes printing processing conforming to the printing output data POD. When the settings contradict each other, the control section 22 notifies a mismatch error to the user and ends the processing. The control section 22 notifies the mismatch error by displaying indication of the mismatch error on the operation panel of the printing apparatus 1. Alternatively, the control section 22 may supply information indicating the mismatch error to the computer 100 at a transmission source of the printing output data POD and cause a display section of the computer 100 to display the information. In the notification of the mismatch error, it is preferable to present measures that can be taken in order to solve the mismatch error. When the user receives the notification of the mismatch error and the measures for solving the mismatch error are executed, the printing apparatus 1 executes the printing processing.
When it is determined in step S120 that paper feeding sections for a cover and a text are individually designated, the processing proceeds to step S130 and the control section 22 determines whether execution of the specific post processing is designated by the post processing designation information FIS. When execution of the specific post processing is not designated, the processing proceeds to step S160 explained above. On the other hand, when execution of the specific post processing is designated, the processing proceeds to step S140 and the control section 22 determines whether a condition determined in advance as a condition for enabling the post processing is satisfied. In the following explanation, the condition for enabling the specific post processing is simply referred to as “post-processing enabling condition”. The post-processing enabling condition is explained below. When the post-processing enabling condition is not satisfied, the processing proceeds to step S170 and the control section 22 executes the notification of the mismatch error. When the post-processing enabling condition is satisfied, the processing proceeds to step S150 and the control executing section 223 controls the printing unit 2 and the post-processing unit 3 and executes printing processing according to the paper feeding section designation information FES and the post-processing designation information FIS irrespective of designation by the paper type designation information PTS of the printing output data POD.
As the post-processing enabling condition, any one of condition examples explained below can be used.
i. The paper type set by the paper-type setting section 221 for the second paper feeding section for the paper for cover designated by the paper feeding section designation information FES coincides with any one of a post-processable plurality of paper types stored in the storing section 222.
In this condition example 1, it is assumed that, as shown in
i. The paper type designated by the paper type designation information PTS is “automatic selection (plain paper)” and the paper type set by the paper-type setting section 221 for the second paper feeding section for the paper for cover designated by the paper feeding section designating information FES coincides with any one of the plurality of post-processable paper types stored in the storing section 222, and
ii. The paper type designated by the paper type designation information PTS is “automatic selection (plain paper)” and the paper type set by the paper-type setting section 221 for the first paper feeding section for the paper for text designated by the paper feeding section designation information FES is the same as the paper type designated by the paper type designation information PTS.
The paper type designation information PTS in i and ii of the condition example 2 is the same “automatic selection”. Concerning ii of the condition example 2, it is assumed that, as shown in
As the post-processing enabling condition, various conditions other than the condition examples 1 and 2 explained above can be set in advance. As the post-processing enabling condition, it is preferable to use a condition including at least i explained above.
As explained with reference to
As explained with reference to
As explained above, when the post-processing designation information FIS designates the selection of the specific post processing and predetermined conditions including a condition that the paper type of the second paper for the cover set by the paper-type setting section 221 coincides with any one of the plurality of paper types stored as being post-processable in the storing section 222 are satisfied, the operation control for controlling the printing unit 2 and the post-processing unit 3 is executed according to the paper feeding section designation information FES and the post-processing designation information FIS irrespective of the designation by the paper type designation information PTS. That is, when the paper type of the second paper for the cover is a paper type for which the specific post processing is possible, the printing and the post processing are performed without using the paper type designated by the paper type designation information PTS. As a result, it is possible to obtain a post-processed print intended by the user.
