I have an HP MFP M177fw LaserJet Pro printer. When printing from my iMac the "media types" that Apple programs show do not match what the HP printer offers.
Matter of fact in the HP set up screen on the "web" Paper Setup allows me to choose from the full line of HP Paper Products. However under "Paper Types" in the set up the selections are only a few listed types rather than the same full line of HP Paper Products.
As I said, my Apple programs list different general paper types. use a work around by setting up a 3 tiered cross reference table. Luckily I only print using "light" paper for most things, HP Glossy Brochure Paper for pictures and card stock for my golf league scorecards. My HP printer is 6 1/2 years old but still going strong. This problem is not really major. Even when the printer and computer were both new the problem was there and I worked around it.
The other problem I have is that the HP wifi antennae can't receive a good signal from my new AT&T router. Too many walls. No problem because I just plugged the printer in using an ethernet cable directly to the iMac. Works fine. I can also print from my iPad or iPhone by selecting the printer wifi.
I loaded the Easy Start on May 5th, 2020, but based on your suggestion, I just tried again. The "Check Box" said that the “Essential Software” was up to date, but that Easy Scan was not. I went ahead and reinstalled Essential Software anyway, but did not reinstall Easy Scan.
Lo and Behold it found that I was using the Apple AirPrint driver and asked me to change to the HP Driver. It solved the problem. All the HP paper products now show up in the Apple Programs.
