Abstract

PURPOSE:To prevent an erroneous printing by executing the save of the printer paper presence or absence information and the set of no paper together with the save of screen information or control information. CONSTITUTION:A terminal equipment 1 has a display 2, a keyboard 3 and a printer 4, which are respectively connected by signal lines 11-13, and the equipment 1 is composed of a control part 5, a memory 6 and a refresh memory 7 and connected to a high order station through a communication line 14. When an interrupting key 15 is pushed down, a processing to be presently executed in the terminal equipment 1 is interrupted and the preceding screen information and control information are respectively stored as save information 8 of a slanting line part in the refresh memory 7 and the memory 6. Further, printer paper presence or absence information 9 are also stored to the save information 8 and after that, the no paper is set to the above-mentioned presence or absence information 9. When a canceling key 16 is pushed down after another processing is ended, the save information 8 are recovered to the refresh memory 7 and the control part 5 and restarted. Thus, even when printing data are generated at a save time, printing operation is not started and the erroneous printing is erased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a bank terminal device having a printer, and particularly when a process using a printer is temporarily interrupted and another process is executed. The present invention relates to a terminal control method suitable for preventing erroneous printing on paper set in a printer in a previous process.

[Conventional technology]

Conventional devices take into consideration the saving and restoring of screen information and control information, as described in Japanese Patent Laid-Open No. 58-40662.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology does not take into account the paper set in the printer, and there is a problem in that during execution of another process, printing may be mistakenly printed on the paper used in the previous process.

An object of the present invention is to solve the above problems and prevent erroneous printing.

[Means for solving problems]

The above purpose is to check the paper presence/absence information when starting the printer's printing operation, and to start the printing operation only when the paper presence/absence information indicates that paper is present. This is achieved by setting the paper presence/absence information to "no paper".

[Effect]

When saving screen information, etc., the printer's paper presence/absence information is temporarily set to "No paper", so even if paper is set, it will be in a state of "No paper" during execution of another process. As a result, even if print data is generated during execution of another process, the printing operation will not be started due to paper out, and printing will not be performed by mistake.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

The terminal device 1 has a display 2. connected by signal lines 11, 12.13, respectively. Keyboard 3. A printer 4 and a control unit 5. It is composed of a memory 6 and a refresh memory 7, and is connected to a higher-level station via a communication line 14.

When the interrupt key 15 is pressed, the process currently being executed on the terminal device 1 is interrupted, and the screen information and control information immediately before the key press are transferred from the refresh memory 7 and the control unit 5 to the signal line 1o.
The information is stored in the memory 6 as the save information 8 in the shaded area. Furthermore, the printer paper presence/absence information 9 in the shaded area in the memory 6 is also stored in the save information 8, and thereafter, the printer paper presence/absence information 9 is set to "No paper". After the above evacuation operation is completed, the terminal device 1 can execute a process different from the interrupted process.

When the release key 16 is pressed after another process is completed, the save information 8
is restored to the refresh memory 7 and the control unit 5 via the signal line 10, and the passbook presence/absence information 9 is similarly restored, allowing the interrupted processing to be resumed.

On the other hand, when print data is generated, the control section 5 checks the printer paper presence information 9, and if paper is present, the control section 5 sends the print data to the printer 4 via the signal line 13 to perform the printing operation, but if there is no paper, the control section 5 checks the printer paper presence information 9. The print data is invalidated and no printing operation is performed.

In this embodiment, the interrupt key 15 and the release key 16 are
This is a key that provides an opportunity for recovery, and can also be grouped together as an interrupt/cancellation key. Furthermore, if it is necessary to notify the higher-level station of the suspension/resumption of processing, it is also possible to send a message via communication@g14 each time. moreover,
If printing becomes necessary during execution of another process, this can be handled by providing means for resetting the paper presence/absence information 9 after paper replacement and clearing the printer paper presence/absence information in the save information 8.

〔Effect of the invention〕

According to the present invention, in addition to saving screen information and control information, printer paper presence/absence information is saved and paper out setting is performed, so in the process after information is saved, paper is out and no print data is generated. Also, no printing is performed, which has the effect of preventing erroneous printing.

Claims (1)

[Claims] 1. In a device consisting of a keyboard, a display, and a printer, while a certain process is being executed, information related to that process is temporarily saved so that another process can be executed, and when the information is saved, the paper presence/absence information of the printer is temporarily saved. As,
By preventing incorrect printing on the paper set in the printer in the previous process while another process is being executed, and by recovering the information saved at the end of the other process and returning the printer's paper presence/absence information to its previous state, it is possible to A terminal control method characterized by providing a means for restarting.
