My HP Laserjet 1100 was working fine in Windows 7 until I received an automatic Windows update. Now the printer shows as Unspecified - Unknown Device. I went to HP to download drivers, and it states that they are included in Windows 7. Microsoft website says to go to the manufacturer for driver download. I'm going around in circles. I know the printer worked, I just need to be be to download the correct drivers. I need help!!
