I've seen quite a few posts about this problem. Here is the solution that worked for me: Go to your control panel. Select Add Printer. When it asks you if you want to add a Local or Network Printer, believe it or not, choose local. Click the "Create a New Port" button, hit next. Then in the box that pops up, enter the printer path (example: \\COMPUTERNAME\PRINTERNAME) Click OK. Search for your printer manufacturer and model, then install. Worked for me like a charm. Windows Vista at its best.
