Abstract

PURPOSE:To enable line-feed width by one piece of line feed function code to be freely set by unit of business processing program by allowing a printer control to have a printer execute line feeding according to a value set in a memory upon the reception of a line feed command. CONSTITUTION:A memory 11 is provided anew in a printer control 2, and a business processing program 3 sends a required line feed width to the printer control 2 prior to the start up of business. The printer control 2 sets this value in the memory 11. For a line feed during the execution of printing, a line feed command is output to the printer control2 from the business processing program 3. This line feed command is executed by sending out a control code to indicate the necessity of line feeding, e.g. 'NL' code to the printer control 2. When the printer control 2 receives 'NL' code, it reads a preset line feed width referring to the memory 11 and performs controls such as enabling a printer 1 to feed paper by an amount corresponding to the readout value. Thus it is possible to freely select the line feed width by a single line feed code and perform free chit form designing without the overall modification of the existing software.

Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] A storage section is provided in a printer control section of a printing device such as a terminal device, and a business processing program sets a desired line feed width in the storage section before starting a business. When the printer control section receives a line feed command, it causes the printing device to execute a line feed according to the value set in the storage section.

[Industrial application field]

The present invention provides a method for controlling a line feed function in a printing device (prior art) A printing device of a terminal device is always provided with a line feed function. This line feed function operates by sending a line feed function code (hereinafter simply abbreviated as line feed code) to the printing device.

Many terminal devices are used in which the line feed width when receiving one "NL" code can be selected from 115 inches and 1/6 inch.

Further, some printing apparatuses are equipped with a hardware switch for selecting between one line and two lines as the line feed width for one "NL" code.

However, in order to reduce cost, recent printing apparatuses have omitted the hardware switch and are now capable of starting only one line.

[Problem that the invention seeks to solve]

To insert a line feed by two lines using such a printing device, use “NL
' Requires two codes.

For this reason, existing software materials that used to have two line breaks with one line feed code now have to change the line feed code to 21, which requires a lot of effort. Furthermore,
When the functions of the printing device are simplified in this way, form design is restricted, and it may become difficult to design a desired form.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a line feed control method for a printing device in which the line feed width based on one line feed function code can be arbitrarily set for each business processing program.

[Means for Solving the Problems] As shown in the figure, the printing device 1 includes a printer control section 2. The printer control unit 2 controls various operations of the printing device based on commands sent from the business processing program 3, and executes desired printing.

In the present invention, a storage section 11 is newly provided in the printer control section 2, and the business processing program 3 sends a desired line feed width to the printer control section 2 before starting a business. The printer control section 2 stores this value in the storage section 11.

When starting a line during printing, a line break command is output from the business processing program 3 to the printer control unit 2. This line feed command is issued by sending a control code, such as a 'NL'' code, to the printer control unit 2L indicating that a line should be broken.

When the printer control section 2 receives the "NL" code, it refers to the storage section 11, reads out the preset line feed width, and controls the printing device 1 to feed the paper by an amount corresponding to this value. conduct.

[For production]

In this way, in the present invention, the line feed width is set in advance for each business processing program, and the actual line feed width is controlled based on this set value, so the line feed width can be set as desired using one line feed code. can do.

〔Example〕

In the series of processes according to the present invention described above, the line feed width and its setting method that are set before the start of a job can take various forms as described below.

First, it is possible to keep the line feed width for one line constant, and to set the number of lines to break using one line feed code.Also, it is possible to set the line break width for one line to be constant, and to set the number of lines to break with one line feed code. The width may be specified by the length, for example, 5 mm.

Furthermore, the present invention can be used regardless of the system configuration, such as in an online system in which at least one terminal device is connected to a host processor, or in cases where a stand-alone personal computer or an intelligent terminal device is used alone. .

In the former case, the business processing program 3 runs on a host processor, and in the latter case, it runs on an independently running terminal device, personal computer, or the like.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to arbitrarily select the width of a line break using a single line feed code, and it is possible to freely design a form without completely changing existing software. , the hardware configuration becomes simple, and therefore the hardware price becomes low.
