The related data structure of USB printer driver is introduced. 介绍了USB打印驱动的相关数据结构。
In this paper, the USB printer driver is implemented by C language in real-time operating system-nucleus. 本文在nucleus实时操作系统上用C语言编码实现了USB打印机(UP)驱动程序。
This technology can also be used to control the USB printer and USB scanner by little modification of driver and data storage application program. 如果对驱动程序和应用程序做适当的修改,还可通过USB主机接口实现对USB接口打印机、USB接口扫描仪等外设的控制。
Based on the analysis of requirement which embedded devices to connect USB printer to print reports, detailed design and coding of the USB printer driver are made in this article. 本文在分析了嵌入式设备连接USB打印机(UP)打印报表这样的需求后,详细设计并编码实现了USB打印驱动程序。
At last, this document illustrates how to fulfill the USB device class program with a USB printer is the target device to be used. 最后用以USB打印机(UP)为目标设备的实例研究了USB设备类的程序实现。
