Design Of Embedded Network Print Server Based On UClinux

With the development of digital information technology and network technology, the embedded system becomes an important part in the computer technology field. The improvement of print technology makes the distributed output in internet become an important aspect of the print device development. Aiming at that the printer normally used is not equipped with network module and has to use a computer to work as the print server. According to the research of embedded system, USB communication technology, network communication technology and file conversion technology, this paper designs an embedded print server to make the printer source be used effectively and to realize the share of the net resource. The server based on the S3C4510B processor works in the uClinux operation system and supports the USB communication.Aiming at the problem that file conversion consumes a great deal of system resource, this paper analyses the question about the memory and the process speed provide by the hardware under the condition of network print server which is consist of ARM development system. This paper adopts the Client/Server print server construction, adjusts the print flow by disposing the file conversion module in client and configures the kernel to make the server slighter. The hardware platform is based on AX4510 embedded system adopting S3C4510B as its core component and the extended USB host port. This design constructs a network print server platform based on uClinux and realizes the function module such as network communication, print manager and USB device driver. In the client, the service fulfills a file conversion module supporting PCL5 and man-machine conversation management.The test shows that the design of embedded network print server achieves the anticipative purpose of supporting network print. The device sharing in internet makes the printer work effectively.
