I have an HP M402dn printer which has started printing the Cantarell
font as blanks; a page using the Cantarell font prints as a perfectly
blank page. The printer has no problem with (eg) the Liberation Sans
font. I believe the problem started recently, possibly with my upgrade
from Fedora-31 to Fedora-32 on about May 17. Questions:
* How can I find out what fonts my printer supports?
* How can I install fonts into the printer?
Thanks in advance - jon
