Can't install network printers

> I have a new laptop running Vista Home Premium and it is connected to my
> home network which has two desktops running XP Pro. I have two printers
> connected to one of the desktops, an HP LaserJet 2200d and a Photosmart 7960
> and both are shared. When I try to install the network printers on the Vista

> and receive the dialog "To use the shared printer \\computername\HPlaser,
> you need to install the printer driver on your computer. If you do not
> recognize or trust the name and location of the printer, do not install the
> driver." When I select "Install driver" I receive a dialog saying "Windows
> cannot connect to the printer. The specified print monitor is unknown". I
> have downloaded the Vista drivers for both printers but can't figure out a
> way to access them when installing the printer. If I install the HP Laser as
> a local printer on the Vista system it installs ok but then I can't figure
> out how to change the port to access the network printer. Hope you can help
> I've run out of ideas.
