【摘要】：打印机作为一种最常用的输出设备,在人们日常生活中发挥着不可替代的作用。针式打印机凭借其独特的打印方式,在一些特殊行业中无法被其他类型打印机替换。打印机技术的发展十分不平衡,主要的核心技术仍掌握在发达国家手中。我国已逐渐掌握了针式打印机的核心技术,具备一定的自主研发能力。随着电子行业和无线网络的不断发展,人们的生活工作方式也在不断的发生变化,对智能、快捷、方便的无线打印设备的需求也更加的强烈；随着蓝牙技术联盟宣布正式采纳蓝牙4.0核心规范,具有极低的运行和待机功耗的蓝牙技术得到了世界的广泛关注,因此,蓝牙技术在打印机行业也得到了广泛的重视和应用。本课题来源于一个针式打印机开发项目,该打印机的系统设计不再使用传统的单片机和CPLD(复杂可编程逻辑器件)组合的打印控制模块,而是利用单独的一片ARM处理器完成打印系统的控制,内置的蓝牙通信模块使得该打印机能够完美支持蓝牙无线打印。本文首先对针式打印机的各部分结构进行了简单介绍,使读者对打印机的工作原理有一个大致的认识,介绍了Windows系统打印体系及功能、Windows系统下打印机驱动的相关技术和组件以及TI(德州仪器)提供的蓝牙低功耗(BLE)协议。本文着重描述作者在项目中承担的具体工作,包括： (1)微软通用打印机驱动程序的开发； (2)在OSAL系统下完成蓝牙虚拟串口通信程序设计； (3)打印机主控芯片与主机间系统交互的开发,实现通过普通的USB接口完成对打印机主控ARM芯片的控制操作。
[Abstract]:As one of the most commonly used output devices, the printer plays an irreplaceable role in people's daily life. Other types of printers cannot be replaced in some special industries. The development of printer technology is very uneven. The main core technology is still in the hands of developed countries. China has gradually grasped the core technology of needle printer and has certain independent R & D capability. With the development of electronic industry and wireless network, people's life and work style is changing constantly, and the demand for intelligent, fast and convenient wireless printing equipment is more intense. With the announcement of the adoption of Bluetooth 4.0 core specification by Bluetooth Technology Alliance, Bluetooth technology with extremely low running and standby power has been widely concerned in the world. Bluetooth technology has also been widely paid attention to and applied in the printer industry. This topic comes from a needle printer development project, the printer system design no longer use the traditional MCU and CPLD (complex Programmable Logic device) combination of print control module. Instead, a single ARM processor is used to control the printing system. The built-in Bluetooth communication module enables the printer to support Bluetooth wireless printing perfectly. In this paper, the structure of the needle printer is introduced briefly, so that the reader has a general understanding of the working principle of the printer, and introduces the printing system and functions of the Windows system. The related technologies and components of printer driver in Windows system and the Bluetooth low power Ble protocol provided by TI (Texas Instruments). This paper emphatically describes the specific work undertaken by the author in the project. Including: 1) the development of Microsoft universal printer driver; 2) Design of Bluetooth virtual serial port communication program under OSAL system; The development of the system interaction between the printer master control chip and the host computer realizes the control operation of the printer master ARM chip through the common USB interface.
