Abstract

PURPOSE:To ensure that a load upon a host computer is reduced by providing a page number generation part which generates a page number corresponding to each page on a printing sheet, and synthesizing print data sent from the host computer, at a page image drawing part and a page number generated at a page number generation part into a bit map data equal to a single page. CONSTITUTION:A print data interpretation part 3 receives print data sent from a host computer 1, and interprets, edits the print data to data in units of page. In addition, a page number generation part 4 generates a page number corresponding to each page of data units of page prepared by the print data interpretation part 3. Further, a page image drawing part 5 synthesizes the data in units of page from the print data interpretation part 3 and a page number from the page number from the page number generation part 4 to prepare bit map data equal to a single page. A mechanical printing part 6 prints the bit map data which is entered from the page image drawing part 5. Consequently, it is possible to reduce a load on the host computer.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a page printer which prints print data received from a host device page by page.

[0002]

2. Description of the Related Art A conventional page printer that prints print data received from a higher-level device page by page and prints the print data on a printing paper spans two or more pages even if the printing data is only one page of the printing paper. Also in this case, it does not have a function of printing each page number for each page of the printing paper, and only prints the received print data.

[0003]

As described above, the conventional page printer for printing the print data received from the host device does not have the function of printing the page number on the printing paper, so the page number is not printed. If you need to print
It is necessary to send print data including print data corresponding to the page number to the page printer from the host device.
Therefore, the higher-level device has to manage the page numbers on the program for creating the print data, which has a drawback that the load of the higher-level device is heavy.

[0004]

A page printer according to the present invention comprises a print data interpreting unit for receiving print data sent from a higher-level device, interpreting / editing the print data, and creating page unit data. A page number generation unit that generates a page number corresponding to each page of the page unit data created by the print data interpretation unit, the page unit data from the print data interpretation unit, and the page number generation unit from the page number generation unit. A page drawing unit that combines the page numbers to create bitmap data for one page; and a print mechanism unit that prints the bitmap data input from the page drawing unit,
Furthermore, an operation unit for setting the presence / absence of a page number, the printing position of the page number, and the printing format of the page number and instructing the page number generation unit is provided, or the print data interpretation unit is provided by It is provided with a function of transmitting to the page number generation unit an instruction regarding the presence or absence of the transmitted page number, the printing position of the page number, and the printing format of the page number.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of the present invention, and FIG. 2 is a plan view showing an example of a result printed by the embodiment of FIG.

The page printer 2 of the embodiment shown in FIG. 1 receives the print data sent from the higher-level device 1, interprets and edits the print data in the print data interpreting unit 3, and converts the page data into page-drawing unit 5 as data. Send to. At this time, the page number generation unit 4 generates a page number corresponding to each page and sends it to the page drawing unit 5. The page drawing section 5 synthesizes the print data sent from the print data interpretation section 3 and the page number sent from the page number generation section 4 to create one page of bitmap data, and prints it. It is sent to the mechanical section 6. The printing mechanism unit 6 prints the bitmap data sent from the page drawing unit 5 on one page of printing paper.

As shown in FIG. 2, a page number 10b is printed on the print result 10 together with the print data 10a sent from the host device 1.

FIG. 3 is a block diagram showing a second embodiment of the present invention.

The page printer 12 shown in FIG. 3 has a print data interpretation unit 13, a page number generation unit 14, and a page drawing unit 1 which have the same functions as the corresponding portions of the embodiment shown in FIG.
5 and the printing mechanism section 16, an operation section 17 is provided. The operation unit 17 determines whether to print a page number when printing print data on a printing sheet (presence or absence of page number),
The printing position of the page number and the page number on the printing paper, and the format when printing the page number can be set, and these set items are instructed to the page number generation unit 14.
The page number generation unit 14 transmits the presence / absence of a page number instructed from the operation unit 17, the print position of the page number, and the print format of the page number to the page drawing unit 15, and the page drawing unit 15
Creates bitmap data by this, and sends it to the printing mechanism unit 16 to print.

FIG. 4 is a block diagram showing a third embodiment of the present invention.

The page printer 22 shown in FIG. 4 has a print data interpretation unit 23, a page number generation unit 24, a page drawing unit 25, and a printing mechanism unit 2 as in the embodiment shown in FIG.
6, the print data interpreting unit 23 interprets the presence / absence of the page number, the print position of the page number, and the print format of the page number transmitted from the higher-level device 1 and interprets them. The information is transmitted to the page number generation unit 24. The page number generation unit 24 includes the page number and the information sent from the print data interpretation unit 23 together with the page number.
Then, the page drawing unit 25 creates bitmap data by this and sends it to the printing mechanism unit 26 for printing.

[0013]

As described above, the page printer of the present invention is provided with the page number generation section for generating the page number corresponding to each page of the printing paper, and the page drawing section from the host device 1 By combining the sent print data and the page number generated by the page number generation unit to create one page of bitmap data, the print data including the print data corresponding to the page number is received from the host device. Even if it does not, there is an effect that the page number can be printed on each page of the printing paper, and therefore there is an effect that the load on the host device can be reduced.
