I am using windows 7. We had a house fire a year ago and now we are trying to piece together what we have and we have 3 or 4 printers and this one is the one we have that still works good. We have it working but we have to have a program that works the printer. We were using the Photosmart 6300 but it is giving us problems so I just switched to the older officejet. We lost a bunch of disks in the move out and back in.
