Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a simultaneous exclusive control method for serial printers [Prior Art] Conventionally, in this type of system, a serial printer device for printing messages and a serial printer for printing forms have been used. The devices are installed separately, and each printout is performed independently.

[Problem to be solved by the invention]

- In the conventional simultaneous exclusive control method for serial printers mentioned above, the serial printer device for printing messages and the serial printer device for printing forms were installed separately. The cost was high.

Also, during system operation, if the serial printer device for printing messages becomes abnormal and cannot print a single page, the serial printer device for printing forms should be able to print both messages and forms. However, if a message request and a form request are made at the same time,
There is a problem that the message print line is printed in the form print line, so that the form print line and the message print line are mixed, making it difficult to see both the message and the form.

SUMMARY OF THE INVENTION An object of the present invention is to reduce the number of serial printer devices, and to simultaneously print messages and forms without mixing message print lines and form print lines with one serial printer device. The objective is to provide an exclusive control method.

[Means for Solving the Problems] A simultaneous exclusive control method for a serial printer according to the present invention: (A) message print information editing means for editing a message based on a message editing request; (B) by the message print information editing means. Message print line output means for outputting the edited message to a serial printer; (C) form print information editing means for editing form print information based on a form editing request; (D) by the form print information editing means. a central processing unit having a form print line output means for outputting the edited form to the serial printer; (E) a serial printer device management table that stores operating status of the serial printer; and (F) the message print information. A fixed magnetic field comprising: a message print line information storage file that temporarily stores the message information edited by the editing means; (G) a form editing request information storage file that temporarily stores the form information edited by the form print information editing means. It is configured with a disk device.

〔Example〕

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

FIG. 1 is a block diagram of one embodiment of the present invention.

The simultaneous exclusive control method of the serial printer shown in Figure 1 is as follows:
Central processing unit 1, serial printer device 2, fixed magnetic disk device 3, message printing line information storage file 4 built in the fixed magnetic disk device 3, form editing request information storage file 5, message printing information editing means 6, message printing It consists of a line output means 7, a form print information editing means 8, a form print line output means 9, and a serial printer management table 10.

Next, the operation will be explained.

The message print line information storage file 4 stores operation records and status change record messages, and the form editing request information storage file 5 stores form editing request information.

Furthermore, in the serial printer device management table 10,
Information indicating whether the serial printer device 2 is "in use" or "on standby" is set.

Next, the operation when a message editing request 11 is made to the message print information editing means 6 will be explained.

When a message editing request 11 is made to the message print information editing means 6, the message print information editing means 6 edits the corresponding message. After editing, the serial printer management table 10 is referred to see if the serial printer 2 is in use.

When the serial printer device management table 10 indicates that the serial printer device 2 is “on standby,” the message print information editing means 6 sets the serial printer device management table 10 to the serial printer device 2 “in use,” and then prints the message. A message print line output request 12 is made to the print line output means 7, and the message is printed out by the serial printer device 2.

The message print information editing means 6 detects the completion of the message printout and outputs the message from the serial printer management table 1.
After setting 0 to serial printer device 2 "standby",
A message print output completion notification 13 is sent to the form print information editing means 8.

If the serial printer device management table 10 indicates that the serial printer device 2 is "in use," the message print information editing means 6 stores the edited message in the message print line information storage file 4. When this message is stored, the number of stored information, which is set in the message print line information storage file 4 and indicates how many pieces of message print line information are currently stored, is set to "71".

Next, the form printing information editing means 8 refers to the serial printer device management table 10 and prints the serial printer device 2.
If it is "on standby", set the serial printer device management table 10 to "in use" for the serial printer device 2, edit the corresponding form printing information, and then send it to the form printing line output means 9. A form print line output request 16 is made, and the form is printed out by the serial printer device 2.

Form print information editing means 8 that detects completion of form print output
After setting the serial printer device 2 to “on standby” in the serial printer device management table 10, it notifies the message print information editing means 6 of the completion of form print output 17.

When the serial printer device management table 10 indicates that the serial printer device 2 is “in use,” the form printing information editing means 8 receives the form editing request 1 made to itself.
5 is stored in the form editing request information storage file 5. When storing this information, the form edit request end ψf' is set in the storage file 5, and the number of stored information indicating how many pieces of form edit request information are currently stored in the form edit request information storage file 5 is set as "+1".

When printing messages or forms after Pi, the printing process for messages or forms that could not be performed because the serial printer device 2 was "in use" will be explained using form printing as an example. Explain the operation.

At the timing when the message print output end notification 13 is sent to the form print information editing means 8, the form print information editing means 8
extracts one piece of form editing information stored from the form editing request information storage file 5. Then, the serial printer device management table 10 is
"In use" and edit and print out the corresponding form. After the completion, the serial printer device management table 10 is set to “standby” for the serial printer device 2, and a form print output completion notification 17 is sent to the message print information editing means 6.
I do.

Furthermore, the message printing + rgWi editing means 6 notifies the form printing information editing means 8 of the completion of the message printing output at the end of the processing, and the form printing information editing means 8 responds to one request at the timing of receiving the notification. Edit and output the corresponding form.

This operation is repeated until there is no longer any form editing request information in the form editing request information storage file 5.

Furthermore, even if a message cannot be printed because the serial printer device 2 is "in use" when printing a message, the edited message stored in the message print line information storage file 4 is retrieved once the form printout is completed. Printed out.

In this way, serial printer device management table 1
0 is used to manage the resources of the serial printer 2 on a first-come, first-served basis, so message print lines are no longer mixed in form print lines.

〔Effect of the invention〕

As explained above, the present invention has the effect that the number of serial printer devices can be reduced by sharing the serial printer devices.

Further, there is an effect that printing can be performed using one serial printer device without mixing message print lines and form print lines.

15... Form editing request, 16... Form print line output request, 17... Form print output completion notification.
