Abstract

(57) [Summary] [PROBLEMS] After a series of printing operations is completed, when there is a blank page in printed paper, it is possible to determine whether it is a correct blank page or an incorrect blank page. Absent.
Therefore, it was not easy to determine from the output printed matter that the page was a blank page that could be removed. SOLUTION: There is provided a means for judging that a command to skip a page has been received from an external device, and information which can be determined to be a blank page created according to an instruction of the external device is added to a blank page created at this time. By printing and printing nothing on blank pages created unnecessarily, it is easy to determine whether the page is a correct blank page or an incorrect blank page.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a printing apparatus for generating and printing output information based on input information from an external device.

[0002]

2. Description of the Related Art Conventionally, as a technique for printing a specific pattern on a blank page, there is JP-A-2-265773. When the transmission failure from an external device occurs during a series of printing and a blank page is created, the technique prints a specific pattern on the blank page and does not output it in a blank state. It is designed to prevent curling. However, a blank page may be intentionally created during a series of printing operations. For example, when performing double-sided printing, the back side may be blank and the next page may be aligned with the front side. Alternatively, there is a case reverse to the above description. These cases are realized by an instruction to skip a page from an external device. However, the data of the blank page may be erroneously created at the stage of generating the output information, the paper may be printed in a multi-layered form on the cut sheet printing apparatus, or the panel or the operator may operate on the continuous paper printing apparatus.
In some cases, a blank page is fed.

[0003]

After a series of printing operations is completed, it cannot be determined from the printed matter whether the page is a correct blank page or an incorrect blank page. Therefore, there is a problem that it cannot be determined whether the output printed matter is a blank page that can be removed.

[0004]

Means for determining that a command to skip a page has been received from an external device,
There is provided a means for printing, on the blank page created at this time, information that can be determined to be a blank page created according to an instruction from an external device.

[0005]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an example of a functional block diagram of a printing apparatus. Various types of print information to be printed are stored in the reception buffer 102 from the external device 101. Receive buffer 102
Is stored in the character pattern buffer 107, the address of the stored character pattern buffer 107 is registered in the character pattern address management table 110, and this table is set to a valid state. If the data stored in the reception buffer 102 is a character code, a figure, image data, or the like, and the editing process 104 is a character code, the address of the character pattern buffer 107 storing the corresponding character pattern is changed to a character pattern address. It is obtained from the management table 110 and written into the page buffer 105. The graphics and image data are also written into the page buffer 105. Drawing processing 106
When the contents of the page buffer 105 are character data to be printed, the character pattern is read from the character pattern buffer 107 and drawn and developed in the frame memory 108. Graphics and image data are also read from the page buffer 105 and rendered and developed in the frame memory 108. When rendering of one page is completed in the frame memory 108, dot data of one page is sent to the printing mechanism 109 and printing is performed. If the received information is a command to skip a page, the editing process 104 generates blank page information and stores it in the page buffer 105. At this time, a character pattern buffer 1 storing a special image pattern that can determine that a blank page has been created according to a command from the external device 101.
The address 07 is stored in the page buffer 105 at the same time.

FIG. 2 shows an example of printing at the time of double-sided printing by a cut sheet type printing apparatus. In this example, each chapter is printed from the front side. Since the document starts from the front surface 21 of the first sheet and the first chapter is contained in the front surface 21 of the first sheet, print control information for skipping the back surface 22 of the first sheet is issued. According to the print control information, the back surface 22 of the first sheet is set as a blank page, and the special image pattern 25 is drawn at any place in the blank page. As a drawing method, there is a method of printing as a normal character, or a method of storing information for drawing a special image pattern 25 in the page buffer 105 and drawing by the drawing processing 106 based on this information. Although not shown, there is a method of printing a document such as “blank page” instead of the special image pattern 25. Thereafter, two chapters are printed from the second surface 23. The second chapter does not fit on the front surface 23 of the second sheet, so that it is printed on the back surface 24 of the second sheet.

FIG. 3 shows a printing example of a continuous paper type printing apparatus. In this example, one blank page is created between jobs. A on the first sheet of paper 31
In the case where all the jobs have been completed and printing has been completed, print control information is issued so that the second sheet 32 becomes a blank page. According to the print control information, the second sheet 32 is set as a blank page, and the special image pattern 25 is drawn at any place in the blank page. In the next B job, printing was started from the third sheet 33 and printing was stopped on the fourth sheet 34, and the printing apparatus stopped for some reason. At this time, printing was continued after the operator fed one sheet of paper. Therefore, a blank page 35 is inserted between the fourth sheet 34 and the fifth sheet 36. In this case, the special image pattern 25 is not printed on the blank page 35. After a series of printing is completed, it is possible to easily remove unnecessary blank pages on which the special image pattern 25 is not printed.

[0009]

As described above, according to the present invention, by printing a special image pattern or a document indicating a blank page on a consciously created blank page, a blank page that is not printed is printed. Can be determined at a glance that the page is created unnecessarily for some reason, and there is an effect that unnecessary blank pages can be easily removed.
