David, I have a month-old Dell Dimension XPS T450. It's a P3. I guess the serial number is on the back somewhere which I can't get to at the moment. Before seeing your msg I had downloaded the latest driver and tried USB again with the same result. Win98 recognizes the printer however there's no communication with the printer. The control panel freezes and end task doesn't even close it. I have to kill Lxroap32 to get it to close or reboot when all else fails. If you absolutely need the serial number I'll look for it. And yes I have to be fair as I've read of many USB problems.
