Share XP printer with Win7`

The easiest way is to open Explorer, enter the IP address of the XP machine with the printer, (like    \\192.168.1.125). That should open a list of shared files … but also any shared printers. Double click on the printer you want the Win7 machine to connect to and it should start the process of adding drivers.

Screw the “add network printer” wizard under printers.
