Control Panel - Printers - Right click the printer you want to use (on the computer it's connected to) - sharing. Enable sharing. Then go to my network places, should pop up. If not, add the printer manually (Add network place link). If there's a problem, close all firewalls. This is assuming you have a network already set up. If you don't, click on the link to set up small/home office network in my network places.
