Embodiment one

An embodiment of the present invention provides a control method for deleting temporary printing data, which can effectively delete the temporary printing data after confirming that printing is completed.

As shown in Figure 2, a control method for deleting and printing temporary data includes:

Step S201, the print driver sends a print job to the image forming device;

Step S202, receiving a completion message fed back by the image forming device; the completion message includes a message that the image forming device has finished receiving the print job or a message that the image forming device has completed outputting the print job;

Step S203, the print driver program deletes the temporary print data of the print job.

Through the embodiments of the present invention, the print driver can delete the temporary printing data when receiving a successful print message from the image forming device or receiving a message that the print job is complete, so as to solve the problem that the user needs to reprint due to an error in the image forming device. Resume printing is cumbersome problem.

The control method of the embodiment of the present invention further includes:

Step S204, when receiving the message that the output print job is completed fed back by the image forming device, the print driver sends a deletion instruction to the image forming device; or, after the print driver deletes its own temporary printing data, it sends The image forming device sends a deletion instruction;

Step S205, the image forming apparatus deletes the temporary print data of the printed print job according to the delete instruction.

According to the embodiment of the present invention, the image forming apparatus deletes the temporary print data generated by the print job according to the instructions of the print driver, so as to ensure the safe processing of the print job and ensure the validity of the deletion. The image forming device body can effectively delete the temporary printing data in the image forming device body after the printing job is completed according to the deletion instruction of the print driver. Especially in case of an internal error in the image forming device, the temporary print data related to the print job cannot be deleted in time, resulting in a safety accident that the data is left behind and the print content is leaked. With the delete instruction of the print driver, it is possible to further ensure the deletion of the temporary print data. Effectiveness, to ensure the safety of printing operations.

Optionally, for the print driver and the image forming device, the deletion period of the temporary print data is described as follows:

1. Image forming device:

a) The opportunity to reply to the print driver for data clearing has the following two situations:

i. After the image forming device has received all the print data of this print task, it notifies the print driver that it should execute the temporary printing data clearing at the driver end;

ii. The image forming device notifies the print driver that it should clear the temporary printing data at the driver end after executing the printing task;

b) The clearing of the temporary printing data by the image forming device must be in the completed state of the print job, or the image forming device is in the idle state. Otherwise, wait for the print task to be completed and execute to clear the temporary printing data;

2. Print driver:

c) The print driver sends a clear command to the image forming device each time it detects that the image forming device is connected, and at the same time executes a clear command to delete the temporary printing data stored by itself;

d) The print driver sends a clear command to the image forming device after detecting that the image forming device finishes executing a certain printing task, so that the image forming device completes the deletion of the temporary printing data.

The above situation c is suitable for the application scenario: when the operating system of the client finds that the image forming device cannot receive the print job, it will store temporary print job data, and when printing resumes after the error is resolved, the operating system will save the print job The data continues to be sent to the print driver to allow the image forming device to continue printing. At this time, the user does not want to continue printing when resuming printing or continuing printing, so the temporarily stored print job data needs to be deleted. In this case, a background monitoring program can be set, which is a part of the print driver, and can monitor the connection of the image forming device and printing errors, and then delete the temporary printing data after the error. For example, on the first day, the user prints the print job. Because the client cannot call the print service and a printing error occurs, the print job is suspended and sent to the image forming device. When the image forming device is turned on the next morning, it is re-established with the client. When connecting, the printing error may have been resolved at this time, and then there will be a situation where the image forming device automatically prints out the print job of the first day after it is turned on. In this case, it does not meet the security and confidentiality requirements, and it is easy to leak the printed content. Therefore, through the embodiment of the present invention, when the print driver monitors the access of the image forming device, it can send a clear command to the image forming device to internally delete the temporary printing data generated by the error stop or the one that has not been deleted has been completed. Print temporary data for printing, or perform deletion of temporary printing data itself.

Through the settings of the above different scenarios, it can be ensured that useless temporary printing data can be deleted no matter on the side of the print driver or the side of the image forming device, so as to prevent printing data from remaining and ensure the confidentiality of the printing operation.
