摘要

Printing and scanning methods using a facsimile machine communicating with a computer over a bi-directional direct passive link connected between digital communication ports of the computer and facsimile machine Upon receipt of an instruction at the facsimile machine, the printing method includes receiving digital image data from the computer via the bi-directional direct passive link. The digital image data is processed substantially as it is received at the facsimile machine and printed onto media. Upon receipt of an instruction at the facsimile machine, the scanning method includes scanning content from media provided within the facsimile machine to create digital image data digital image data representative of the content, and providing the digital image data substantially as it is created to the computer via the bi-directional direct passive link. The instructions and digital image data are transmitted in a standard facsimile machine format using standard facsimile machine protocols.
