My printer has a parallel port and a usb port. Can I connect and print from two different computers ? -

using these two ports. Ex. My home PC connected with the parallel port and my laptop with the usb port?

You can do that only if your computers won t run at the same time with the printer switched on because even if you are not printing anything your printer and one of the computers are permanently sending a connection signal.At this point if another computer is blocking this signal by sending it s own the printer is confused.It s a little bit complicated.I hope I made myself understood.

Yes. Me amp; my friend do that in my office.
