Development of Embedded Network Print System Based on ARM7

A technical grade network print system used in power protection equipment is developed. It makes the ordinary printer a independent device in the local area network, reduces costs and makes the job in the network print be more flexible and more convenient. The researched system adopted ARM7 microprocessor within which implanting μC/OS-Ⅱ real time operating system, constructing a hardware platform of embedded network print system on the LPC2378 chip, and having a deep development and implement in the overall design feature and application design of the system. The results of field application experiments indicate that the developed network print system works stably and reliably, and the system also has such advantages as convenient design and installation, strong real-time performance in practice.
