Abstract

PURPOSE:To enable print data to be sent from a computer side to be output to a continuous sheet without use of a sheet feeder and, in the same easy manner, to a cut sheet such as a cut slip with of the sheet feeder by automatically setting a left margin at a printing start position for a printing sheet fed from the sheet feeder. CONSTITUTION:A firm ware interprets whether a printing process should be performed against a printing sheet fed from a sheet feeder, and if the interpretation is affirmative, interprets whether a dip switch for selecting between the addition of a left margin and the non-addition is turned ON. If the dip switch for selecting whether the left margin should be added is turned ON, a space equal to the left margin for a printing sheet is automatically added to a space before the print data of each line which is sent from a computer. Then printing each line is activated based on the added space equal to the left margin and print data sent from the computer.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a left margin control method for a printer, and particularly to a left margin control method for a printer capable of mounting a sheet feeder.

[Conventional technology]

The left margin control method for conventional printers that can be equipped with a cut sheet feeder is that the sheet feeder feeds print paper to the center of the printer, so either the left margin is set in the print data sent from the computer, or the left margin is set for each line. The printing operation was performed by adding a space for the left margin at the beginning of the line.

[Problem to be solved by the invention]

The left margin control method of the conventional printer mentioned above is
It is necessary to set a left margin for the print data sent from the computer or add a space for the left margin at the beginning of each line, so depending on whether the printer uses a sheet feeder or not, the computer This method has the disadvantage that the print data output to the printer must be changed on the side.

An object of the present invention is to automatically set the left margin of the print start position for the print paper sucked from the sheet feeder when the printer side is turned on when printing on the print paper sucked from the sheet feeder. This allows the printer's left margin control to make the print data sent from the computer the same for continuous paper that does not use a sheet feeder and for cut sheets such as single sheets that use a sheet feeder. The purpose is to provide a method.

[Means to solve the problem]

A left margin control method for a printer according to a first aspect of the present invention is a left margin control method for a printer capable of mounting a sheet feeder, in which: (A) determining whether or not a printing operation is performed on printing paper sucked from the sheet feeder; (B) Determine whether or not a switch for selecting whether to add a left margin is on; (C) A printing operation is performed on the printing paper sucked from the sheet feeder, and the switch is on. (D) A space corresponding to the left margin of the print paper sucked from the sheet feeder is automatically added before each line of print data sent from the computer; It is constructed by performing a printing operation for each line in response to print data sent from a computer.

Further, in the left margin control method of the printer of the second invention, in the left margin control method of the printer capable of mounting a sheet feeder, (A) it is determined whether or not the printing operation is performed on the printing paper sucked from the sheet feeder. CB) a second determining means that determines whether a switch for selecting whether or not to add a left margin is on; When it is determined that the printing operation is to be performed on the printing paper sucked from the feeder, and the second determining means determines that the switch is on, the left margin of the printing start position on the printing paper sucked from the sheet feeder is determined. (D) a printing operation starting means for setting the print start position set by the left margin setting means to perform a printing operation for each line of print data sent from the printer. It is composed of

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a flowchart showing an embodiment of a left margin control method for a printer according to the present invention. Further, FIG. 2 is an external view showing an example of a printer equipped with a sheet feeder.

As shown in FIG. 2, in a printer equipped with a sheet feeder, the sheet feeder supplies printing paper to a central position of the printer.

In this embodiment, as shown in FIG. 1, the firmware first determines in step S1 whether or not a printing operation is to be performed on printing paper sucked from a sheet feeder.

In step S1, if the printing operation is performed on the printing paper sucked from the sheet feeder (Y), step S2
Then, it is determined whether the dip switch for selecting whether or not to add a left margin is on.

Then, in step S2, if the deep switch for selecting whether to add a left margin is on (Y), in step S3, the sheet feeder is A space corresponding to the left margin is automatically added to the print paper sucked in, and the process moves to step S4.

In addition, in step S, if the printing operation is not performed on the printing paper sucked from the sheet feeder (N), and in step S2, the dip switch for selecting whether to add a left margin is off (N). If so, the process immediately moves to step S4.

Therefore, in step S4, the printing operation is started, and the printing operation for each line is performed on the added left margin space and the print data sent from the computer.

Then, in step S5, it is determined whether all the printing data sent from the computer has been completed. If not all of the printing data has been completed (N), the process returns to step S1, and if all of the printing data has been completed (Y), has stopped.

〔Effect of the invention〕

As explained above, in the left margin control method of the printer of the present invention, when printing on print paper drawn from the sheet feeder, when the printer side is turned on, the printer prints on the print paper drawn from the sheet feeder. By automatically setting the left margin of the start position, the print data sent from the computer side is the same whether it is output on continuous paper without a sheet feeder or on cut sheets such as single sheets using a sheet feeder. This has the effect of making the printer much easier to use.

[Brief explanation of drawings]

FIG. 1 is a flowchart showing an embodiment of a left margin control method for a printer according to the present invention, and FIG. 2 is an external view showing an example of a printer equipped with a sheet feeder.

Claims (1)
