The one suggestion I did not try was installing the HP driver software from a new admin user account. I tried most of the many suggested workarounds/fixes, including the ones you've mentioned. The printer driver would sometimes spontaneously forget it had the duplex unit also. At the same time I also began having issues with the printer occasionally printing blank pages that actually had print (multi-page documents, single-page documents, sometimes even the printer's Test Page print utility). In retrospect I believe the trouble started when my computer was updated from Windto 1903 in June. I have an HP Photosmart C6280 all-in-one printer. I also began getting the 'HP Solution Center cannot run because your device installation is not complete' error in Windows 10 for no apparent reason. HP Solution Center 14 definitely still works with Windows 10 version 1909. Scanner function, which requires the HP Solution Center software that is not launching. The 6500 printer has been working nicely over a hard wired network.

Is it possible that a recent MS security update in Sept or Oct 2019 has the same problem? There were several security updates done. There are a number of older posts that talked about Microsoft security updates that interfered with HP Solution Center and by removing the security update, HP Solution Center worked. I uninstalled HP solution center and the printer SW and drivers, reinstalled and did not solve the problem. I just now went to use it and get 'HP Solution Center cannot run because your device installation is not complete', plus a couple of more messages.

It has been working nicely when I last used it to scan documents approx 2 months ago. I have been running Windows 10 on my desktop and using HP Solution Center for 3 years or more, through upgrade from Win 7.
