A tiny good thing.

Apple is upgrading its OS to 10.13 - High Sierra. That is normally a warning signal. The upgrade to Sierra, 10.12, disconnected my printer from the OS and I could get the printer to function, but could not get the scanner to work.

In preparation for the imminent arrival, I started checking compatibilities, installed the new driver and ... the printer now scans.

My printer is an old Epson Artisan 720, always low on the totem pole for priorities. Windows first, with all its flavors and later, if the chairman of the Epson board had been in a good moon, the Mac updates could be allowed.

I guess the chairman got lucky. Things can be scanned again.
