Wireless Access

I was told by the person who sold me my printer that I could hook it up wirelessly so I can print from any of the 3 computers in my house. How do I do this?? I have the photosmartC4480. My hardwired computer is running XP and is connected to the printer. My laptop is wireless and has vista.

Not directly. Very new printers have wireless builtin. Older printers can connect to wireless routers. Your printer must connect by USB to a computer. It seems you have the latter already.

I have connected Vista laptops to XP desktops several times:

Also I found some info on the new CS forum:
