Abstract

PURPOSE:To simultaneously print both sides by providing an information storage unit for storing information of two pages, and an information output controller for recognizing the information and outputting the information to front and rear face printers. CONSTITUTION:Information to be printed from a central processing unit 101 is received by a control system 201, and stored in an information storage unit 211. An information output controller 212 counts the information stored in the unit 211 so as to sort the information to front and rear face printers 301, 302, recognizes the head of the information of second page, alternately outputs, when the fact that the information of two pages is stored in the unit 211 is judged, the head of first page of the unit 211 to the printer 301 and the head of second page of the unit 211 to the printer 302, and outputs the information of one pages simultaneously to both front and rear faces. The printers 301, 302 substantially simultaneously start printings to simultaneously print both front and rear faces.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control system for a page printer, and more particularly to a control system for a page printer during simultaneous double-sided printing in a printing system of a printer as an output device.

[Conventional technology]

Conventionally, this type of page printer control system prints when one page's worth of information is complete.

[Problem to be solved by the invention]

The conventional printing method described above works in units of one page, so when you want to print one or more pages of information using both sides of the paper, you first print one page of information, then insert the paper again. The drawback is that the next page of information must be reprinted.

[Means to solve the problem]

The page printer control system of the present invention includes an information storage means for storing two pages of information for simultaneous double-sided printing, and an information storage means for storing two pages of information for simultaneous double-sided printing in a page printer that is an output device that outputs information from a central processing unit. The information output control means performs control for distributing the information to the front side printing section and the back side printing section.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.

In FIG. 1, this embodiment includes a central processing unit 101 that outputs information to be printed to a printer, a page printer control system 201 that enables simultaneous double-sided printing,
It has a front side printing section 301 and a back side printing section 302 respectively defined for the front side and the back side, the information storage section 211 stores information from the central processing unit 101, and the information output control section 212 stores information from the central processing unit 101. The printed information is distributed to the front side printing section 301 and the back side printing section 302.

First, the control system 201 of the printer capable of simultaneous double-sided printing receives information to be printed from the central processing unit 101 and stores it in the information storage unit 211 . The information output control unit 212 counts the information stored in the information storage unit 211 in order to distribute the information to the front side printing unit 301 and the back side printing unit 302, recognizes the beginning of the information on the second page, and outputs the information on the second page. When it is determined that the information of
Output alternately from the top of the second page of 1,
The front side printing unit 301 and the back side printing unit 302, which output one page of information simultaneously on the back side, start printing almost simultaneously, making it possible to print on both sides at the same time.

〔Effect of the invention〕

As explained above, the present invention has an information storage unit that stores two pages of information and an information output control unit that recognizes the information and outputs the information to the front and back printing units. This has the effect of allowing simultaneous double-sided printing.
