I was trying to do this with the printer shared on an XP machine:
Now the printer is plugged directly into the MacBook Pro w/USB.
But the same thing is happening.
The hp website provides for this printer on a Mac.
The Mac sees the printer just fine and it seems to print.
But the printer doesn't respond - although it surely does when connected to a PC.
The Mac is going to be the only computer so I have to make it work.
