Set Up Windows 7 to Share a Printer
Windows can share a printer with other PCs on your network, so anyone in your network can connect as long as your printer and PCs are on. Here's how to set up this sharing in Windows 7.
Open Devices and Printers from the Start Menu, and double-click your printer. Pick Customize your printer, and click the Sharing tab in the following window. Select the Share this printer checkbox.
Unless you're connecting a bunch of similar PCs, I recommend skipping the option to download additional printer drivers on the host system. Just take a moment to configure everything once on each client. With different combinations of 32- and 64-bit Vista, Windows 7, and XP PCs, it's more hassle than it's worth to try to plan ahead here. Approve the options and close the Properties window.
