Abstract

PURPOSE:To perform automatic printing on a continuous business form and on a slip, by automatically retracting the continuous business form and automatically performing a process for the slip when a slip command is received, and automatically loading the business form when the business form is in a retracted condition upon receiving a continuous business form command. CONSTITUTION:A printer comprises a printer-controlling circuit and a printer mechanism part. When a slip drawing-in command is received, a printer controlling circuit checks whether a continuous business form is set, and when the continuous business form is set, the circuit executes a process for retracting the continuous business form and then a process for drawing in a slip. When a printing or line feeding command is received in the condition where the slip paper is discharged, it is checked whether the continuous business form is set, and when the business form is not set, the business form is automatically loaded, and is line fed to an initial position, followed by executing the printing or line feeding command received.

Description

[Detailed Description of the Invention] [Summary] In a printer capable of continuous ledger printing and cut sheet printing, when a cut command is received, the continuous ledger is automatically saved, the cut sheet is automatically processed, and the continuous ledger sheet printing is performed. When the command is received, if the continuous ledger is in the evacuation state, the continuous ledger will be automatically loaded,
This is a printer control method that executes a command after starting a new line to the original position. This makes it possible to automatically print continuous forms and slips without operator intervention.

[Industrial application field]

The present invention relates to a control system for a printer that can perform continuous form printing or single form printing in accordance with instructions from a computer on the main body side.

[Conventional technology]

Printers capable of continuous sheet printing and single sheet printing are well known. In conventional printers of this type, when attempting to process single sheets, the operator operated a predetermined switch/lever in order to evacuate the continuous sheets. Furthermore, when returning to the continuous book processing, the operator visually performs an operation to return the continuous book to its original position.

[Problem to be solved]

The above-mentioned conventional technology requires operator intervention when switching from continuous sheet processing to single sheet processing and from single sheet processing to continuous sheet processing, which has the disadvantage of placing a heavy burden on the operator. did.

The present invention was created in view of this point, and even when performing continuous form printing, even if cut sheets are processed in the middle,
The purpose of this invention is to provide a printer control method that allows smooth return to the original continuous paper processing.

[Means for solving problems]

FIG. 1 is a diagram showing the principle of the present invention. As shown in FIG. 1(a), the printer has a printer control circuit and a printer mechanism. The printer control circuit is microprocessor controlled, and the printer mechanism is capable of continuous sheet printing and ticket printing. The printer control circuit is the first
Processing as shown in Figure (b) is performed. That is, when a ticket suction command is received, it is checked whether or not the continuous sheet is set, and if the continuous sheet is set, a process is performed to save the continuous sheet, and then a process is performed to suck the ticket. I do. In addition, if a print or line feed command is received while the cut sheet is being ejected, it is checked whether the continuous sheet is set or not.
If the continuous book is not set, the continuous book is automatically loaded, a line feed process is performed to the original position, and then the received print command or line feed command is executed.

〔Example〕

FIG. 2 is a diagram showing an example of an electric circuit of a printer. In the figure, 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,
Reference numeral 8 indicates an input port, 9 an address decoder, and 10 a bidirectional driver/receiver.

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 on the main body side. microprocessor 1
can send data to the console panel or the driver and mechanism section 6 via the output port door, and can read data from the console panel or the driver and mechanism section 6 via the input port 8.

FIG. 3 is a diagram showing an example of the configuration of the printer mechanism section. In the figure, 11 is a print head, 12 is a platen, 13 is a hopper, 14 is a stuffing force, 15 is a tractor, 16 to 21 are inserter rollers, and 22 is a paper feed roller. Furthermore, solid line arrows indicate the direction of travel of the continuous book, and dotted line arrows indicate the direction of travel of the ticket.

Normal continuous form printing is performed as follows. tractor 15
The continuous ledger is pulled out by the inserter roller 18.
By rotation of 19, the printing start base single line of continuous book is set to print head 1.
1 and printing is performed.

Normal ticket printing is performed as follows.

The sheet is taken out from the hopper 13 by the rotation of the paper feed roller, and the print starting line of the sheet is positioned below the printing pad 11 by the rotation of the inserter rollers 20 and 21.
Printing/line feed is performed, inserter roller 16 or 1
By the rotation of 9, it is discharged to the stacker 14.

FIG. 4 is a diagram showing the flow of processing performed by the printer of the present invention. A program for executing the process shown in FIG. 4 is stored in the control memory 3.

■ Check whether a command has been received. If no command is received, wait until a command is received.

■ Check whether it is a single inhalation command. When the result is Y (Yes), the process ``■'' is performed, and when the result is N (No), the process ``■'' is performed.

■ Check whether the continuous ledger is set. When the result is Y, the process ``■'' is performed, and when the result is N, the process ``■'' is performed. Note that the continuous book set state indicates a state in which a continuous book is present on the platen 12. This is detected by a photosensor or the like.

■ Reverse line feed of the continuous book to the initial set state and store the amount of reverse line feed in register A.

■ Set the continuous ledger to save state. The continuous book retracted state refers to a state in which the tip of the continuous book slightly rests on the tractor 15.

■ Inhale the single ticket.

■ Perform printing/editing operations as necessary.

■ Eject single slips. Return to ■.

■ Check whether the continuous ledger is set. When Y, 0 processing is performed, and when N, [phase] processing is performed.

[Phase] Automatically load the continuous book and set it to the initial cent state.

■ Automatically feed a line in the positive direction by the amount of line feed stored in register A.

[Phase] Execute the print/line feed command. Return to ■.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, it is possible to switch from continuous sheet printing to cut sheet printing and from sheet printing to continuous sheet printing without operator intervention.
