Abstract

PURPOSE:To apply printing on paper having a proper size by automatically selecting paper having a necessary size on the basis of printing data. CONSTITUTION:A decoder part 1 interprets the printing data sent from a host apparatus and judges the size of the printing result of the data prior to printing to determine the min. paper size necessary for printing and controls a paper feed mechanism 2 on the basis of the paper size. The paper feed mechanism 2 supplies paper having a proper size from an upper hopper 3 or a lower hopper 4 under the control of the decoder part 1.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a printer, Regarding.

[Conventional technology]

In conventional page printers, in particular, the selection of paper for the page printer was performed by an operator's operation or by a dedicated command for paper selection.

[Problem to be solved by the invention]

In the conventional page printers mentioned above, selecting paper requires an operation by the operator or a dedicated command for paper selection, so the operation is performed every time the paper is changed, or paper selection commands are added to the print data. The drawback is that you have to do it.

[Means to solve the problem]

The page printer of the present invention includes a paper feed mechanism that selectively feeds paper from any one of a plurality of hoppers, and a paper feed mechanism that interprets print data sent from a host device and uses the minimum necessary amount to print the data. and a decoding section that determines the paper size of the paper.

〔Example〕

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

FIG. 1 shows the configuration of an embodiment of the present invention. The decoding unit 1 interprets the print data sent from the host device, determines the size of the print result of the data prior to printing, and determines the minimum paper size necessary for printing.
The paper feed mechanism 2 is controlled based on the paper size. The paper feeding mechanism 2 feeds paper of an appropriate size from the upper hopper 3 or the lower hopper 4 under the control of the decoding section 1.

〔Effect of the invention〕

As explained above, the present invention has a function to automatically select and print paper of the required size based on the print data, so that the operator can perform operations and the print data has a dedicated paper selection function. This has the effect of being able to print on paper of an appropriate size without adding any commands.

Claims (1)

[Claims] Multiple hoppers, a paper feeding mechanism for selectively feeding paper from any one of the multiple hoppers, and the minimum necessary to interpret print data sent from a host device and print that data. What is claimed is: 1. A page printer comprising: a decoding unit that determines a limited paper size; and a function of automatically selecting and printing paper of a required size based on print data.
