At present, the printer through the parallel port, USB interface to connect with the computer, which can support USB interface for maximum speed of around 12Mbps Print speed, parallel port can be the maximum print speed of around 1Mbps only, so if the network printer to support the USB interface connector, then , we should allow it to interface with the computer through the USB connection.

目前打印机可以通过并口、USB接口来与电脑连接，其中USB接口可以支持最大速度为12Mbps左右的打印速率，并口所能达到的最大打印速率只有1Mbps左右，因此如果网络打印机支持USB接口连接的话，我们就应该让它通过USB接口与计算机连接。

Fu days billion of Electronic Science and Technology Co., Ltd., was founded in early 1991, in Shenzhen, the solar wind developed on the basis of the company to produce integrated wiring network products (including crystal head, jumper, network tools, patch panel, module panels, etc.), computer peripherals (USB lights, USB fan, USB data cable USB series products, etc.), environmental protection and energy saving rechargeable LED eye protection desk lamp, LED rechargeable flashlight, three series of products.

First, we analyse USB communication methods, and there are three important methods; Second, we discuss the whole software structure and communication protocols and design a basic protocol model based on embedded environment. Then, we explain the implementation of a file transport system based on this model. Through the comprehensive utilization of StrongARM UDC and Linux USB modules, we complete a portable protocol stack. Moreover, the function of the system is tested under the Windows and Linux OS.This thesis provides us with a full description on the realization of the USB mass storage system.
