You need a wireless print server that uses the same broadcast standard as your router (wireless-b, g, or a).
Check the wireless print server mfg website to see if your printer is listed as being compatible with the wireless print server model.
I have my wireless routher in one room with a laptop nearby, and another laptop in another room. The printer is in the third room (has to be there bc my housemate and I share it). I can catch a wireless signal in the third room. Is there some sort of wireless adapter I can rig to the printer? If so, how? THANK YOU
