Epson print-scan-copy-fax for Catalina
Doing a quick search of the Epson site, it looks like only two models still have Fax (that's usually that few multifunction printers still include.
I found this model:  WorkForce Pro WF-3733 All-in-One Printer
There is also a WF-3730 ... I'm not sure what the difference is between the 3733 and the 3730.
I have an (old) Epson Artisan 837 which has all those features, but while that printer is no longer produced, Epson has been updating the drivers for it ... I was still able to get the driver for Catalina.
These days I'm not so much a fan of Inkjets (with except of some professional photo printers that use pigment based inks) and prefer color lasers (which have really come down in price).  But this bias because I'm tired of inkjet printheads drying up and wasting a lot of ink trying to clear the head.  If the printer is used frequently enough, it's not really an issue.
