kingmarianne,
If I read it right, you were able to print in the past. What changed? Did you change printers? USB ports can be usb1 or usb2. If your old printer worked and the new one doesn't, your usb ports are most likley the older usb1 type and the new printer might require a usb2 (high speed)hub. You didn't supply enough information for any real help. Good luck
PEACE
