Jimtherev,
I must point out that I did mention the fact that only one pc at a time can control the peripheral in my post:
"I should just point out that only one pc can have "ownership" of a device at any time, unlike an office printer where tasks are queued, but this isn't a problem for a SOHO environment. "Ownership" is via a small app that runs on each pc on the network which shows the devices available and their status. Connecting/disconnecting to a device takes a second or so."
I doubt you'll find any print server will offer anything better as we are, after all, talking about devices designed to operate over usb connected to a single pc.
Perhaps you need to improve your communication skills - ie learn to shout to each other across the room/house!
Best wishes.
