HP laserjet pro, 400 dm 451
HP color laser jet Pro M277
Both worked with initial upgrade (10 to 11) then killed.
I contacted MS advisors and one suggested changing location from 1 or 2 to higher #s Since September, Since the second upgradeI had no access to prinrters but use a laptop Win 10 to do the work.I have conrtacted Dell, HP and Microsoft withut success. Both puters are Dell, hooked up with USB cordsand a Linksys router. They have not bee moved.
One suggestion was to downgrade the 11 to 10
The upgrade denies that LaserJet pro 400 is NOT seen on screen Win 11 . It works well with Win 10
