Abstract

PURPOSE:To manage a page memory with a memory size suitable for each paper size to effectively use the intrinsic page memory by providing a page change-over control part for changing over the size of the page memory and the page memory for storing printing data for a maximum paper size printiable by an engine. CONSTITUTION:Where a maximum printing size is A3, data is normally stored in a page memory 4 set to a size A3 through a page change-over control part 1. When data for one page is stored in the page memory 4, the data is transmitted to an engine part 5 through a data delivery control part 2. The data is printed under the control by an engine control part 3. When data for a size B4 is transmitted, the page memory 4 which has been managed so far is changed to a size B4 by the page change-over control part 1 so as to store data for one page or more therein, and the page memory 4 is managed and controlled. Therefore, a larger amount of printing data can be stored with decreasing paper size, and the page memory can be effectively used.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to page printers.

[Conventional technology]

Conventional page printers have recently become rapidly popular due to their low noise and high speed printing capabilities.

However, conventional page printers of this type either have a page memory for the maximum paper size that can be printed, or do not use the page memory effectively when printing on a size smaller than the maximum paper size. was.

[Problem to be solved by the invention]

Previously, there was no problem when printing on the maximum paper size, but when printing on paper smaller than the maximum size, the page memory was left unused, so the page memory available at Kiku was not used effectively. There are drawbacks.

[Means to solve the problem]

The page printer of the present invention includes an engine section, a control I-roll section for controlling the engine section, and a data sending control section for sending data to the engine. It has the page memory that stores print data for the maximum paper size that can be printed by the engine.

〔Example〕

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

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

FIG. 2 is a diagram showing a memory management method according to an embodiment of the tree invention.

As an example, the maximum print size is assumed to be A3.

Normally, data passes through the page switching control section 1 and is stored in the page memory 4 set to A3 size.
The image is transferred to the engine section 5 and printed while being controlled by the engine control section 3.

Next, when B4 size data is sent, the page switching control unit 1 transfers the page memory 4 that has been managed until now to B4.
The page memory 4 is managed and controlled by changing the size to 4 (FIG. 2) so that data of 1 page or more can be stored.

〔Effect of the invention〕

As explained above, according to the paper printer of the present invention,
By managing the basic memory with a memory size suitable for each paper size, when printing at a size smaller than the maximum print paper size, the print data becomes smaller as the paper size becomes smaller. This has the effect of storing a large number of pages and making effective use of page memory.
