If you use vista and have a wireless network, then I will tell you how to network any old printer to a wireless network. you must have the printer plugged in to a computer. Even though vista sucks I have 2 computers with vista (I downgraded the laptop to xp)
What you need: 2 computers with vista 1 with wi-fi, a printer, a wireless home network, and the know-how which will be provided
Step 1: Set It Up... Part 1
go to the start menu. type in without quotes "network and sharing center" completely. click the first option. then click the drop-down arrow that says "printer Sharing". The default is off, so press the on button, then click apply. a warning box should pop up click ok
Step 2: Set It Up... Part 2
Go to your laptop. then find a document. When you print , click add printer. then click the name of the computer and then click the name of the printer you want to print on. WHEN YOU PRINT, MAKE SURE THE HOST COMPUTER IS ON!!!!!
