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 invention 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.

The specific process of the application program driving the printing output device to execute the printing operation comprises the following steps:

the application program receives the setting information of a user and determines a file to be printed and printing information;

after receiving a printing instruction triggered by a user, the application program is in butt joint with a standard interface of a printing control program to call the SDK and issues the printing instruction comprising the file to be printed and the printing information;

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.

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.

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 firstly execute the printing operation corresponding to the newly started printing instruction, and then continuously execute the printing operation corresponding to the previously received printing instruction.

In a further scheme 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 default driver is modified from the system printing service program to a print control program after the operating system is 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.

The specific process of modifying the default driver by the operating system comprises the following steps:

after the intelligent operating system is started, a printing control program is automatically started, and a request for adding a custom printing service is sent to the intelligent operating system;

and the intelligent 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.
