I had a similar problem and after checking Google I found the following
procedure and it worked do it on the Vista machine;


"I had the same problem. I found a solution. Logically it makes no sense to
me, but it worked so...

Go to Control Panel. Choose printer. Then choose Add Printer.

ChooseAdd a local printer. Click on Create a new port. The default in the
drop down box is Local Port. Do not change that. Click Next.

A dialogue box will appear asking for you to enter a port name. Type in the
\\computer name\printer name ie. My computer's name is basement and the
printer name is EpsonSty so I typed in \\basement\epsonsty."

Hope it works for you.
