Can anyone look/confirm that Microsoft seems to have removed most of their Type 4 printer drivers for HP LaserJet printers from Windows Update? Specifically I was looking to move an HP Color LaserJet 4600N printer to another Windows 2012R2 server today and when I hit the "search Windows Update," it did not return the driver I was expecting in the list (HP Color LaserJet 4600 PS Class Driver). I've Googled until my fingers bled but I can't find anything other than HP says "check Windows Update if you want Type 4 drivers." I know it was previously offered because I have it on my existing print server.
Good to hear that the driver came back. You might want to follow the steps in the section titled Download the driver for later use or use on another computer in the following support document. That way you'll have a copy of the driver in case this happens again:
