Digital BW, The Print

I normally print B&W on a 7600. The PC (win2k) communicates to it over 
Ethernet. But I've got a tiny bit of color work to do, so I borrowed a 
2200 printer. My only choices for connecting to it are parallel or USB, 
so naturally I picked on USB.

I spent a couple of days getting it installed, what with OS upgrades 
(win2k, fully patched), loading the driver from the Epson website, doing 
the funny little dance if you have a certain "hot fix" patch installed, 
etc. But, I got it to work. It's been printing fine for a couple of weeks.

Today it printed fine too, for a while. Then I switched images. When I 
tried to print this image, the first time it got half way through and 
quit. No errors. Nothing in the event log. It left no clues. Second try, 
same thing. It got about half an inch farther along this time.

I played with the USB cable (plug and unplug), rebooted the printer and 
the computer. Now when I try to print from Photoshop, I get a 
"communication error" pop-up. Still nothing in any of the logs to give 
me a clue as to what is actually wrong.

Finally, I deleted the printer and did a reinstall of the printer 
driver. Same symptom.

I've run through all my ideas. Would any of you 2000 / windows / USB 
users please tell me what you think could be causing this?
