I have a Windows 7 64 bit system and have just installed a new 968 All in One Printer. I cannot get it to print from Word or Outlook even though it is set as the default printer and I downloaded the Windows 7 64 bit driver. I've carried out all the usual checks and turned things on and off but none of it makes any difference. I also have Avast anti-virus and wondered whether that was interfering but it made no difference when I disabled it! I've tried phoning Dell support and hung on for ages but nothing. I've also spent hours looking at the on-line support, again zilch. HELP!
