I'm not entirely sure what you mean by "protocol", but I think you're referring to the stream of printing codes sent from the computer to the printer. > This area needs a little clarification.

So the only change would be in the physical connection. Not even close. A computer needs a special driver to communicate with a USB printer connected to it. Since this is commonly part of the OS, you don't usually think of it, but it's there nonetheless. The computer needs a different driver to communicate with a network adapter. In reverse, your printer has drivers to decode the incoming signal from your computer. It has no idea of how to decode the incoming signal from a network adapter. As a simple example of that lack of functionality, how would you tell your printer to set an IP address on the network adapter attached to it? Short answer: you can't. Your printer has no concept of a network stack. -- Kirk Strauser _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
