Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, based on the examples herein, which are within the scope of the application as defined by the claims, will be within the scope of the application as defined by the claims.

Referring to fig. 1, fig. 1 is a flowchart of a control method of a printer according to an embodiment of the present application. The embodiment provides a control method of a printer, and as shown in the figure, the method specifically includes the following steps:

and step 11, receiving a network connection request sent by the client, and establishing network connection with the client according to the network connection request.

In the implementation, the printer may be used as an execution body, and the network connection between the printer and the client may be realized by receiving the network connection signal sent by the client. For example, the printer is a bluetooth printer, and the user can utilize the mobile phone as a client to establish connection with the bluetooth printer through bluetooth, so that the bluetooth printer and the mobile phone can perform data interaction.

Step 12, receiving a print request sent by the client, and detecting whether the current running state is in a non-print working state.

After establishing a network connection with the client, a print request sent by the client may be received, and when the print request is received, it is detected whether the current running state is in a print state and whether the current running state is in other working states. The detection in this case may confirm whether the printer is currently executing the printing function on the one hand, and whether the printer is executing other non-printing functions on the other hand.

If the current printer is executing the printing function, the received printing request can be processed according to the existing printing processing mode; if the printer is in an operating state in which other non-printing functions are being performed, step 13 is performed.

The non-print job status may include a scan status and a cable status, among others.

And 13, establishing an asynchronous thread.

In order to enable the printer to still perform printing work when the printer is in other working states, after confirming that the printer is in a non-printing working state, a queue of asynchronous threads can be created by establishing the asynchronous threads to process subsequent printing tasks. Thus, the main thread can continue to execute the non-printing work, and the asynchronous thread is specially used for processing the printing work, so that the printing and other operations can be synchronously performed.

And 14, receiving the print tasks sent by the client, and sequentially sending the print tasks to a processing queue of an asynchronous thread for printing.

When implemented, the print job may be multiple. During the period of establishing the network connection relation with the client, once the print task sent by the client is received, the received print task is sent to a processing queue of an asynchronous thread to be sequenced and waited until being printed.

In this embodiment, a network connection relationship is established with the client according to a received network connection request sent by the client, so as to lay a network foundation for realizing data interaction with the client. After receiving a print request sent by a client, detecting whether the current running state is in a non-print work state so as to confirm whether other works are being performed while no print work is currently performed. If the printing job is currently in a non-printing job state, i.e., while no printing job is currently being performed, other jobs are being performed, at this time, an asynchronous thread is established so that the printing job can be performed while the other jobs are not being affected. After receiving the print tasks sent by the client, the print tasks are sequentially sent to a processing queue of an asynchronous thread for printing. Therefore, the synchronous execution of the printing work and the non-printing work of the printer can be realized, the operation time is saved, and the working efficiency of operators is effectively improved.

In particular, the main body of execution of the control method of the printer may be the printer, or may be a functional module based on software and/or hardware in the printer, or may be another device, or the like.

In order to facilitate the user to know the printing progress of the print job in real time, in some embodiments, after receiving the print job sent by the client, the control method of the printer may further include: and acquiring the processing state of the print task and updating the processing state to the client.

In particular, in printing a plurality of print jobs, the printer can only process one print job at a time, so that the plurality of print jobs in the processing queue are ordered and waiting. After the processing states of the plurality of printing tasks are acquired, the processing states can be updated to the client in real time, and the display interface of the client can display the printing information of each printing task. The printing information may include: identification information of the print job, processing status, and time of print job setup. Wherein each print job has its unique identification information. Therefore, the user can know the processing condition of each print task in real time according to the print information updated to the client, and the logistic staff can check the print tasks more conveniently.

In some embodiments, when the print tasks are sequentially sent to the processing queue of the asynchronous thread for printing, the method specifically may include the following steps: determining a current print job in a processing queue; acquiring corresponding printing data according to the current printing task and printing; and after detecting that the current print task is finished, sending a callback instruction to process the next print task until the print task in the processing queue is processed.

When the problem of asynchronous threads is solved, a scheme of multi-core threads in a control method of the printer can be realized based on a multithreading optimization technology (GRAND CENTRAL DISPATCH, GCD) packaged by a C language. GCD is mainly used for optimizing concurrent tasks which can be executed in a thread pool mode by a program supporting multi-core processor. After determining to use the GCD, since the print jobs placed in the processing queue are essentially combined data, which is composed of CPCL instructions, the printer can be used as the execution body to make the corresponding print operation by recognizing these CPCL instructions, and the processing queue needs to process one print job and throw the callback instructions after the printer processes the next print job. Since callbacks are themselves asynchronous, in order to enable the processing queue to process the printer's callbacks one by one, a semaphore mechanism in the GCD can be introduced. Similar to the semaphore consuming mechanism in an operating system, when implemented, a semaphore is created first and then the print job is allowed to consume the created semaphore. In the process of consuming the semaphore, other print tasks always wait for the semaphore to be consumed until the print tasks consume the semaphore, so that the problem that the processing queue in the asynchronous thread executes the print work is solved, and the effective and independent execution of the print work is ensured.

In some embodiments, when acquiring corresponding print data and printing according to the current print job, the following steps may be specifically performed: according to the current print task, calling print data corresponding to the current print task from the client; if the call is successful, the print data is cached in the processing queue for printing.

When the printer is used for printing, the printer firstly acquires corresponding printing data from a client establishing a network link relation according to the current printing task, and caches the acquired printing data in the processing queue for printing.

However, under the influence of multiple factors from the outside, there may be a case where the printer fails to acquire print data. To this end, the control method of the printer may further include: if the calling fails, marking the current printing task as printing failure, and ending the current printing task. So as to continuously process the subsequent printing tasks, and ensure the printing efficiency while not affecting the whole printing process.

Accordingly, after the end of the current print job is detected, the completion condition of the print job can be detected. If the successful completion of the current print task is detected, a successful callback instruction can be sent to the client to inform the client of completing the current print task, and meanwhile, preparation can be made for next step of retrieving the print data. If the current print task is not successfully completed, acquiring the failure reason, and sending the failure reason and a failed callback instruction to the client so that the client can upload the failure reason to the server and display the failure reason to the user, so that the user can be reminded when the server performs backup work, and the user can conveniently respond according to the failure reason.

In some embodiments, the control method of the printer may further include: receiving a print job interrupt request sent by a client; searching a print task corresponding to the print task interrupt request from the processing queue, and detecting the processing state of the corresponding print task; if the processing state is the state to be printed, deleting the corresponding printing task from the processing queue; if the processing state is the printing state, stopping printing the current printing task and ending the current printing task. Thus, after the user sends out the print job, the user can interrupt some or all of the print jobs according to the own demand.

In addition, the client can end the print task by interrupting the network connection. When the printer is implemented, after the client interrupts the currently established network connection relationship, the printer cannot acquire the print data from the client through the print task in the processing queue, and the print data acquisition fails, and the print task is ended.

Likewise, accidents such as the APP being killed, the printer being powered off, abnormal or irregular operation of the printer system, etc. may also cause the printing to be interrupted, which may result in printing failure. In order to cope with such unexpected situations, the print data of the client may be backed up in advance and synchronously backed up to the corresponding server, so as to facilitate the loss of the print data. Or after the printer acquires the print task, the printer can immediately call the corresponding print data, and the print task and the corresponding print data are put into a processing queue for printing processing.
