This should be easily taken care of in Windows Network Setup Wizard--when you run Network Setup Wizard on the main computer with the printer attached, you should get the option to turn on File and Printer Sharing--to share the printer over the network. If both computers are connected to the same wireless device, you should be seeing the printer attached to the main computer if you are looking in your laptop--if you go to start -> control panel -> Printers and faxes. The printer should be identified by the name of the printer and then by what computer it's connected to. I don't think you'll have to buy any hardware, and certainly you won't need to buy a print server. As long as the main computer stays on when you want to print, you should be golden. Hope that helps.
