Abstract

PURPOSE:To save printing sheets by providing a printing mode setting section in which a page-feed instruction is forcibly altered to a line-feed instruction. CONSTITUTION:Printing information 5 is sent to a printing section 2 as printing data after it has been stored in a memory circuit 1. A printing mode setting section has a switch for setting a normal mode and a debugging mode, and when the normal mode is set, printing is performed in accordance with printing control signals 6 sent from a debug processing device. When the debugging mode is set, a printing control circuit 4 forcibly alters a page-feed instruction out of the printing control signals 6 from a data processing device to a line-feed instruction by means of a printing mode signal 9 and generates a control signal 8 so as to control the printing section 2. That is, although the printing section 2 is supposed to original feeds pages so as to start printing, instead the printing section 2 feeds lines and then continues printing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device, and particularly to a printing device aimed at saving printing paper.

[Conventional technology]

Conventionally, in this type of printing apparatus, as shown in FIG. 2, printing information 23 from a data processing apparatus is first stored in a storage circuit 20. On the other hand, the print control signal 24 is input to the print control circuit 21, becomes a control signal 26, and controls the print section 22.
Print data 25 from memory circuit 20 is printed.

[Problem that the invention seeks to solve]

In the conventional printing device described above, when a page break instruction is received from the data processing device, the page break is performed and printed, so even when print output data is required for reference during program debugging etc. There are cases where several lines are printed on a page and a page break is performed, which has the disadvantage of wasting a lot of printing paper.

[Means for solving problems]

The printing device of the present invention includes a storage circuit that stores print information from a data processing device, a print control circuit that controls printing based on a print control signal from the data processing device, and a printing section that prints print data. The printing device is configured to include a print mode setting section that forcibly changes a page break instruction to a line feed instruction.

〔Example〕

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

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

Print information 5 from the data processing device is stored in the storage circuit 1 and then sent to the printing unit 2 as print data. on the other hand,
The print mode setting section has a switch for setting a normal mode and a debug mode, and when the normal mode is set, printing is performed according to a print control signal 6 from a debug processing device as shown in conventional print information 5.

When the debug mode is set, the print control circuit 4 generates a control signal 8 by forcibly changing the page feed instruction in the print control signal 6 from the data processing device to a line feed instruction in response to the print mode signal 9. Control 2.

In other words, the printing unit 2 prints by starting a new line instead of printing by starting a new page.

〔Effect of the invention〕

As explained above, the present invention has a print mode setting section for changing a page break instruction to a line feed instruction, and by setting the debug mode, print output data can be changed to a reference level during a program debugging period, etc. This has the effect of saving printing paper when needed.
