have your printer hooked up to your dell desktop via usb, then you will need a wireless router, a wireless card for your laptop (most new laptops have one built in). Once you have that, hook up your desktop and modem to the wireless router via an ethernet cord, then set up DHCP on your router (it should tell you how to do it in the manual). Once that is done, both your laptop and desktop should be able to get online, if so, then go on your desktop PC and go to the printer setup page (in control panel), and right click and select "share". Then go on your laptop, and the printer should automatically be detected, and your ready to go! This is assuming that both comps are running windows xp.
