I had a HP 4780 or something similar. I had a stock Windows HP laptop with nothing more than what HP gave me. After a week of futzing I returned the printer for another make. The other make installed on the first try.
I wonder what model you have.
I'm trying to solve a problem for a customer that has Vista Home and a
HP wireless printer. They have tried for a while to install without
success. I thought it was going to be an easy wireless issue but found
it wasn't. The laptop she has see's the printer fine. Sometimes it will
add the printer but the printer will never print. If you try to edit the
configuration it errors. If you try to add another instance of the
printer it will either say ...
"Unable to install printer. Some driver files are missing or incorrect etc"
Or it will error "The printer installation failed. Operation could not
be completed" I did some research and found that it might be that there
are 3 WSD ports showing in the ports list, but I can't delete them. I
tried using them to add another generic printer and then deleting it but
it won't let me.
Can anyone help?
