We've got a network at work and we have an HP Office Jet G85xi All-In-One product, and 5 computers, 2 of which have modems. Now...I can fax from the systems with the modems through the modem and I can fax through the computer with the fax machine (HP Office Jet)

Now what I'm trying to do is be able to fax from other computers on the Network. I tried sharing the HP fax driver from the cmoputer that it was hooked too, but it didn't work. Is there anything special I have to do? Or is there a way to share the modems, so that any computer can fax to them? Or is there a fax program that can fax to any available modem?
