Wireless Router?

my main computer is hooked up to a wireless router. My 2nd computer has an adapter for the wireless router. How can i print something out of my 2nd computer and have it come out of the printer of my main computer?|||Share the printer on the first computer (right click on the printer and click on "Sharing"). Then add that printer to the second computer as a "Network Printer" and you're done.|||program it to do so through the control panel|||http://www.microsoft.com/windowsxp/using鈥?/a>
