摘要
蓝牙,作为一种短距离无线通信技术,近年来越来越受到人们的青睐。蓝牙打印机接口卡用于取代计算机与打印机之间的电缆,实现打印机的无线打印,通过该接口卡可以使多台计算机共享一台打印机,为人们的工作、生活带来了诸多方便。设计主要采用单片计算机、蓝牙等电路,对蓝牙打印机接口卡的软硬件设计方法进行了阐述。测试表明,该打印机接口卡可用于所有具有并行接口的通用打印机(LPT打印机)。
Bluetooth,as a short-range wireless communication technology,attracts more and more attention in recent years.The Bluetooth printer interface card is used for replacing the cable in connection of the computer and printer,and it allows multiple computers,through the card,to share a printer,thus could bring various conveniences to the people’s life and work.The hardware and software of the Bluetooth printer interface card is mainly designed by a single-chip computer,Bluetooth and other circuits,and the detailed description is also given.Test shows that the Bluetooth printer interface card is applicable for all general-purpose printer with a parallel interface（LPT printer）.
