Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides that when the computer of the main system executes continuous form processing software (referred to as continuous form processing software), a document specified by the continuous form processing software is The present invention relates to a printer device that prints using a cut-sheet processing printer.

[Conventional technology and problems]

In order to continuously control a cut-sheet processing printer that handles single-sheet sheets, paper feed commands and ejection commands are required in addition to print commands and line feed commands. Therefore, continuous sheet processing software that issues only line feed commands as print commands is required. Even if the software is executed on the computer of the main system, the document cannot be printed on the slip processing printer. Therefore, when trying to print a document on a single-sheet processing printer using the main unit's continuous paper processing software, it is necessary to check the number of lines on one page and the relationship between the first line printing position and the paper feed position of the printer. This is extremely difficult to implement, as each printer used must be managed by the main system's software, and the continuous paper processing software must be changed so that paper feed commands and ejection commands are issued at calculated timings.

[Purpose of the invention]

The present invention is based on the above considerations, and includes:
To provide a printer device in which, when continuous document processing software that issues print commands and line feed commands is executed on a computer of the main body, a document specified by this continuous document processing software can be printed by a slip processing printer device. The purpose is to

[Embodiments of the invention]

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

FIG. 1 is a diagram showing the hardware configuration of an example of a printer used in the present invention. In FIG. 1, 1 is a microprocessor, 2 is a RAM, 3 is a control memory, 4 is an interface control circuit, 5 is a console panel, 6 is a driver & mechanism section, 7 is an output port, 8 is an input port, 9 is an address decoder, 10 to 12 are bidirectional drivers/receivers, and 13 and 14 are digital switches, respectively.

The microprocessor 1 executes programs stored in the control memory 3.
The RAM 2 has a buffer area for temporarily holding data, a work area, and the like. The interface control circuit 4 controls data transfer with the computer of the main system. Microprocessor 1
is connected to console panel 5 via output port 7.
It is also possible to send data to the console panel 5 and the driver and mechanism section 6, and to read data from the console panel 5 and the driver and mechanism section 6 via the input port 8. The digital switch 13 indicates the page length, that is, the number of lines per page, and the digital switch 14 indicates the reference line for starting printing. Microprocessor 1 reads the contents of digital switches 13 and 14, sets the contents of digital switch 13 in the a register, and sets the contents of digital switch 14 in the b register.

FIG. 2 shows the relationship between the digital switches 13 and 14 and the cut sheet. In FIG. 2, s indicates a cut sheet. The digital switch 13 is a digital switch indicating the number of lines on the paper s.
A switch 14 indicates a print start reference line. In the illustrated example, digital switch 13 indicates a numerical value of 66, and digital switch 14 indicates a numerical value of 3.

FIG. 3 illustrates a cut-sheet processing printer. In FIG. 3, 15 is a print head, 16 is a hopper, 17 is a stacker, 18 is a platen, and 19 is a print head.
2 shows a pick roller, 20 to 24 a feed roller, and 25 and 26 a sensor, respectively.
The automatic feeding of the cut sheet s is performed as follows.

(b) The hopper 16 rises.

(b) The pick roller 19 rotates and the cut sheet s
is taken out from the hopper 16.

(c) The feed rollers 20 and 21 rotate to feed the cut sheet s to the sensor 25, and further send the cut sheet s a predetermined distance from there.

The state after automatic paper feeding is performed is shown in FIG. 3B. For example, if the digital switch 14 is set to the number 3, the cut sheet s will be as shown in Figure 3 (b).
The data is sent to the third line from the position shown in . Paper ejection is performed as follows.

(a) Platen 18, feed rollers 22, 23, 2
4 rotates.

(b) After the trailing edge of the paper s passes the sensor 26,
Further, the paper s is sent by a predetermined distance.

Note that some ticket processing printers use a cassette instead of a hopper.

In the ticket processing printer of the present invention, the following processing is performed. After the power is turned on, when a print command or line feed command is issued for the first time, the paper s is automatically fed, the paper is sent to the print start reference line specified by the digital switch 14, and then the print or line feed command operation is executed. After that, printing or line feed is performed in the same way as continuous paper processing, and when the cumulative amount of paper feed exceeds the number of lines per page specified by the digital switch 13, the paper s is automatically ejected. , automatically feeds the next paper, feeds the paper by the amount that exceeds it, and performs the same operations as for the first page for subsequent printing, line feed, and connection processing to the next page.

FIG. 4 is a diagram showing details of the flow of processing performed by the slip processing printer of the present invention to support the passbook processing software of the main system. A program for executing the process shown in FIG. 4 is stored in the control memory 3. Alternatively, it is a part that performs paper feed command proxy processing, a part that performs command execution processing, or a part that performs ejection and paper feeding processing.

When the power is turned on, a predetermined initialization process is performed, and the program of the microprocessor 1 is
The counter points to address X. When a command is sent from the main system while the microprocessor 1 is in a predetermined state, it is checked to see if it is a paper feed command, and if it is Yes, execution of a conventional cut processing program is started. Ru. Note that when a paper feed command is received, if paper remains under the print head without being ejected, the paper is ejected and then the paper is automatically fed. When an ejection command is sent from the main system, a predetermined instruction sequence in the ticket processing program is executed, and then the microprocessor 1 returns to the state after the initialization process. Processing is performed when the command sent from the main system is not a paper feed command. Print commands or line feed commands are temporarily suspended.

Check whether it is a print or line feed command. If Yes, processing is performed.

The hopper automatically feeds paper from the cassette.

Feed the paper to line b and transfer the contents of register b to register d.

Prepares to execute the received command before feeding paper.

Check whether a print command should be executed. If Yes, perform the process; if No, perform the process.

Perform printing operation.

Check whether a newline command should be executed. If Yes, perform the process; if No, return to step.

When the number of line breaks is C, the value obtained by adding C to the contents of the d register is set in the d register.

Check whether the contents of the d register are greater than the contents of the a register. If the answer is No, perform the process, and if the answer is Yes, perform the process.

Send paper by C lines.

Eject the paper into the stacker.

Automatically feeds paper from the hopper or cassette.

Feed the paper by the number of lines corresponding to d-a. Note that after performing the or processing, the subsequent processing is performed every time a command is sent from the main system.
