We're using Windows Vista.
Our 6540 HP Deskjet Printer
It printed earlier today.
We added an HP Officejet 6210 All in One and the scanner works. The printer in the All-in-one never worked.
Wasn't printing after we hooked up the 6210
There was an error on the control panel -> printers page - said "Error" next to Deskjet 6540
Deleted the 6540 from control panel printers.
Now we can't get the 6540 going again. When we unplug and plug in the USB cable, no "Add New Hardware" bubble pops up. We run "Add new hardware" and nothing happens.
What do we do next?
