|'so please be very specific in any help you may give'|
goes both ways - you have not been very specific! what actually happens when you try to print? Do you get any error messages on the PC? If so, what are they? Does nothing happen at all?
When you say you can scan and copy do you mean from the PC or just using the buttons on the printer? There are several things that may have happened:-
1. If the copy function is actually printing the copy, then the print functionality of the printer is ok.
2. if you can scan and copy from the PC, then the connectivity is ok. Otherwise it could be the USB cable or the printer's usb interface that's the problem. if its the interface then it would be cheaper to buy a new printer than having it repaired.
If 1 and 2 obtain, then likely problem is the print spooler service on the PC - but in this case you should have had error messages.
If you post back with additional information, we can hopefully help you.
