My printer stopped printing! I've reinstalled printer software. I moved the printer to another computer and it works fine. I hooked up another 2175 to this computer and it dose the same thing. It will send a page thew but no printing. I can go to Toolbox and print a test page and it prints, I've even reformatted the hard drive, installed the printer software. Still the same problem. My computer is a Dell Pavilion running Windows XP. Any Ideas?
