Without knowing the details of why the power supply was replaced, I'll 
just mention that I recently replaced a Power Supply that went bad. When 
the PS  gave up the ghost, it must have put out a power surge. I ended 
up reloading the OS, replacing the motherboard, replacing the keyboard, 
and replacing the mouse. Some possible bad news is that your motherboard 
could be damaged or your printer could be damaged or both. If you have 
some other USB devices (camera, flash drive, etc.), try them out with 
the computer. If they also don't work, it is likely the motherboard is 
damaged.

Good luck.
