Embodiment Construction

[0029] The invention provides a Zigbee-based transmission and printing method and system on Android. The method and system create a printer daemon process by developing the App and user space, and through the printer daemon process, the App can obtain the status information of the printing device in real time, and then realize transmission and printing through Zigbee, which is suitable for mobile terminals to operate the printing device. easy and convenient.

[0030] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] Such as figure 1 Shown is a flow chart of the Zigbee-based transmission and printing method on Android according to the first em...

Abstract

The invention provides a method for Zigbee-based transmission and printing on Android. The method comprises the steps that: S1, an App sends a printing request to a user space; S2, the user space creates a printer daemon process; S3, after receiving the printing request, the printer daemon process in the user space accesses a Zigbee drive module to establish connection; S4, according to a printer protocol, the printer daemon process scans a printing device and inquires the corresponding printing device state information; S5, after acquiring the printing device state information, the printer daemon process sends a corresponding state to the App; S6, after acquiring the printing device state information, the App sends to-be-printed printing documents to the printer daemon process; S7, according to the printer protocol, the printer daemon process sends the printing request and the printing documents to the printing device via the Zigbee module. The invention also provides a corresponding system. The method and the system allow a mobile terminal to operate a printing device and are simple and convenient.

Description

technical field [0001] The present invention relates to the technical field of Android system, and more specifically, relates to a Zigbee-based transmission and printing method and system on Android. Background technique [0002] Android (Android System) is an open source mobile operating system based on Linux, mainly used for mobile devices, and is under continuous leadership and development by the Open Handset Alliance (OHA, Open Handset Alliance) established by Google (Google). The Android system is widely customized as an operating system for various devices due to its open source features, including medical devices such as ultrasonic diagnostic instruments. In addition, different from general-purpose Android devices, Android-customized devices generally only run the App (Application, application program) used to control the device on the application layer, and the UI (User Interface) of the App will completely occupy the display interface. [0003] At the same time, wi...
