Hello Christine
Yes, sometimes it can be hard to get Vista to connect to a shared printer
I know of a method which worked with another brand of printer, so let`s try it.
You will have to reinstall the printer driver though to try this method.
1 Uninstall the printer driver again, then...
2 Reinstall the driver on your Windows Vista computer. During installation, you’ll be prompted to connect the printer to your computer. Choose the option to proceed with installation without connecting the printer.
3.After installation completes, open the Printers applet from the Windows Vista Control Panel.
4.Right-click on the printer and choose Properties.
5.Go to the Ports tab.
6.Click Add Port…, select Local Port, then click New Port…
7.For the port name, enter
exactly the network path and share name of your printer
e.g. \\RECEPTION\
Dell 720
(use the proper name of the printer)
8.Click OK, and double-check that this new port is selected with the checkbox next to it.
9.Click OK to close the printer properties.
