I have a 802.11g router w/ 2 win xp pro systems hardwired to it. They both have the same admin account and password. They are currently sharing a USB printer that's connected to system 1. My mom just got a new laptop w/ a built-in wireless card and can't connect to the printer for some reason unless I enter the password for system 1. I created a new account for her on my computer with rights to print only and that didn't work. How do I fix this?
