When it says "User Intervention Required," that means that the printer cannot (or
temporarily was not abled to) be located on the network and Windows has so kindly
placed the printer in offline mode (which doesn't work at all so what's it for?).
All you need to do is right-click on the printer icon (My Computer -> Printers) and
uncheck the line that says "Use Printer Offline." If there is an icon of a printer
in the system tray (lower-right hand corner of the screen), double click on it.
Then from the menu, select "Printer" then "Work Offline."
