Can't print - 'Backend' failed Using a MBP running Catalina 10.15.6 I am unable to print to a networked Xerox printer.  It discovers it just fine with Bonjour, connects, but when I print anything, it instantly pauses the printer, and in the printer job list dialog, it fails saying Ready to Print - 'Backend' failed, 2 pages.
I've tried re-adding the printer, Reset the printing system with the right-click in the printer list, rebooting the machine.  I have an old iMac also running 10.15.6 which can print to it, so I know the printer works.  Any other ideas?
I figured out a workaround.  (Of course after struggling with this for weeks, I figure it out just after posting the question.)
When adding the printer, the dialog asks for &quot;Name&quot;, &quot;Location&quot; and &quot;Use&quot;.  &quot;Use&quot; defaults to &quot;Secure AirPrint&quot;, but changing this to &quot;AirPrint&quot; fixes the problem.  It's a Xerox printer, FWIW.
