Example one
As shown in fig. 1, the present embodiment provides a portable intelligent printing apparatus, which includes an operating system and a print output device, wherein a print control program is written in the operating system, and the print output device is used for executing a printing operation.

and the switching unit is used for disconnecting the drive port of the printing output equipment from the output port of the system printing service program and connecting the drive port of the printing output equipment to the output port of the printing control program after receiving the request of adding the custom printing service.
In the above-mentioned solution, the portable intelligent printing apparatus includes a system print driving unit for providing a system print service program, and when the SDK matching with the print output device has been embedded in the application installed in the operating system, the printing function can be realized by calling the system print service program.
In this embodiment, the printing control program with the SDK is written in the operating system, and the default driver for driving the printing output device is modified to the printing control program by the setting switching unit, so that the application program in which the SDK is not embedded can drive the printing output device to implement the printing function through the printing control program. When the operating system of the portable intelligent printer of this embodiment is written, only the rewritten printing control program is added by using the existing operating system in the prior art, such as an Android system, and meanwhile, the switching unit is added to implement the substitute operation of the printing control program on the system printing service, so that the purpose of no longer embedding the SDK in the application program can be achieved. And a brand-new operating system does not need to be opened again, and the method is easy to realize.
In a further aspect of this embodiment, the portable intelligent printing apparatus further includes:
a feedback information sending unit for sending feedback information according to the running state of the printing output equipment;
and the display unit is used for displaying the printing state of the file to be printed.
Specifically, the feedback information sending unit sends feedback information to an application program which issues a corresponding printing instruction, and the application program marks the printing state of the file to be printed according to the feedback information and displays the printing state through the display unit.
In the scheme, the portable intelligent printing device can acquire the running state of the printing output equipment and display the printing state of the file to be printed to the user, so that the user can know the printing work progress in real time and use the file conveniently.
The embodiment also provides a control method of the portable intelligent printing device. After an application program installed in an operating system of the portable intelligent printing device receives a printing instruction triggered by a user, the SDK is called through a standard interface of the printing control program, so that the printing output equipment is driven to execute printing operation.
As shown in fig. 2, the specific process of the application driving the print output device to perform the printing operation includes:

The printing control program is written into the operating system, so that application programs developed by different manufacturers can be installed in the operating system of the portable intelligent printing device of the embodiment and can be printed by using the printing output equipment, the printing control program provides a standard interface in butt joint with the operating system, the application programs installed in the operating system can be directly in butt joint with the standard interface, and improvement on the printing control program is not needed. Therefore, the scheme of the embodiment improves the compatibility of the portable intelligent printing device to different application programs, and the application programs developed by a third party can be installed and used, so that the printing function can be realized.
On the other hand, the SDK is only integrated in the printing control program and is not embedded in the application program, when the SDK is updated, the printing control program only needs to be updated correspondingly, all the application programs using the printing function are not required to be updated synchronously, and the management of a plurality of application programs by an operating system is more convenient.
In a further aspect of this embodiment, the print control program further sends feedback information to the application program according to an operating state of the print output apparatus.
Preferably, the application program displays the printing state of the file to be printed through a display unit of the portable intelligent printing device according to the feedback information.
In the scheme, the printing control program can also acquire the running state of the printing output equipment and further send the feedback information, and the application program acquires the printing state of the file to be printed according to the feedback information and displays the printing state through the display unit, so that a user can conveniently know the printing state of the file to be printed in time.
Specifically, the feedback information includes "the print output apparatus is occupied", "the print output apparatus is in operation", "the print output apparatus is failed", "the print output apparatus is completed in operation", and the like. And if the current feedback information is 'the printing output equipment is occupied', the application program marks the file to be printed as 'waiting for printing' and displays the file through the display unit. And if the current feedback information is 'the printing output equipment is running', the application program marks the file to be printed as 'printing' and displays the file to be printed through the display unit. And if the current feedback information is 'failure of printing output equipment', the application program marks the file to be printed as 'printing failure' and displays the file to be printed through the display unit. And if the current feedback information is that the printing output equipment finishes running, the application program marks the file to be printed as 'printing finished' and displays the file through the display unit.
In a further aspect of this embodiment, the print control program, when receiving a plurality of print instructions, drives the print output apparatus to perform a plurality of print operations in a predetermined order.
Preferably, the printing instruction further includes a printing priority level, and the printing control program drives the printing output device to execute the corresponding printing operation in order of the printing priority level from high to low.
Preferably, for different print instructions of the same print priority level, the print control program drives the print output apparatus to execute the corresponding print operations in the order in which the print instructions are triggered.
In the above scheme, the printing control program drives the printing output device to execute a plurality of printing operations according to a predetermined sequence, so as to prevent the printing instructions from colliding and influencing the working process of the printing output device.
The printing control program controls the order of the printing operations executed by the printing output device according to the level of the printing priority level, wherein the printing priority level can be set by a user in advance, for example, the priority level is set in advance for a plurality of application programs, and the higher the priority level of the application program is, the higher the printing priority level of the issued printing instruction is.
The user may also set the print priority level when triggering a print instruction. For example, the print control program has received a plurality of print commands, and the print output apparatus is executing a print operation corresponding to one print command, at which time the user triggers another print command and sets its print priority level to the highest. After the printing output device finishes the currently executed printing operation, the printing control program drives the printing output device to execute the printing operation corresponding to the newly started printing instruction, and then to continue to execute the printing operation corresponding to the previously received printing instruction.
In a further aspect of this embodiment, a system printing service program is preset in the operating system as a default driver for driving the print output device, and the operating system modifies the default driver from the system printing service program to a print control program after being started.
Preferably, the operating system is an Android system, and the standard interface is an Android system standard API.
In the prior art, most of the intelligent terminals adopt an Android system as an operating system, and the Android system is selected as the operating system of the portable intelligent printing device in the embodiment, so that most of application programs on the market can be compatible. A system printing service program is preset in an existing Android system to provide a printing function, but the existing Android system does not have an SDK, and the driving of a printing output device can be realized only by embedding the SDK in an application program.
In this embodiment, the printing control program is written into the operating system, and the printing control program can drive the printing output device instead of a system printing service program preset in the operating system, thereby realizing the compatibility of the portable intelligent printing device with an application program developed by a third party. In the scheme, the newly written printing control program is directly added into the existing operating system without rewriting the whole operating system and deleting the program in the existing operating system, so that the method is easy to realize.
As shown in fig. 3, the specific process of the operating system modifying the default driver includes:
after the operating system is started, the printing control program is automatically started, and a request for adding the custom printing service is sent to the operating system;
and the operating system receives the request for adding the custom printing service, disconnects the drive port of the printing output device from the output port of the system printing service program and connects the drive port of the printing output device to the output port of the printing control program.
In the scheme, the printing control program is automatically started after the operating system is started, and the automatic modification of the default driving program is realized by sending the request for adding the custom printing service, so that the user operation is not needed, the method is more intelligent, and the use by the user is facilitated.
