Hi, I was using the printer when i was in xp. But when i switched on to windows 7, the printer even it is on, it shows printer offline in the status bar. The diagnostic tool also report that printer is off Turn it on. But i could not turn it on. Please help I was taking copies for the past few days in the same system, ie. windows 7. Online connection to HP site also does not solve, as it says that there is no separate download for this obselete 3900 series. Should i have to throw the printer away?
