PRINTING SYSTEM AND PCI DEVICE

摘要

A printing system includes a computer with an operating system, and a PCI device communicating with the computer. The PCI device includes a receiving module, a detection module, an installing module and a program module. The program module stores a printer driver program compatible with the computer operating system. The receiving module is capable of receiving instructions sent to the PCI device from the computer operating system. The detection module is capable of detecting whether there is a printer driver program for an attached printer stored in the computer after the receiving module receives the instructions. The installing module is capable of installing the printer driver program stored by the program module onto the computer if the proper printer driver program is not detected in the computer by the detection module.
