Digital BW, The Print

Both of the printers are connected directly to USB ports on the 
computer, I probably shouldn't have used the term "hub" although I 
think that the computer only has one controller for the USB ports and 
that's really the same as a hub anyway. I think connecting one 
printer to the parallel port will solve the problem.

a separate USB port and put the 1280 on the parallel.  I have not had 
any problems installing them on XP though--both are on separate USB 
ports.
