[CentOS] non-functioning printer

In an attempt to diagnose a friend's HP Deskjet D1420,
I'm running a Centos 6.10 LiveDVD.
The readily visible symptom is that it will
accept a job and claim to be printing it,
but nothing ever gets printed, not even a test page.
The same happens on her Ubuntu system.

I recently learned that a blinking power light means
that the printer is complaining about something.
"If an error message appears
Read the error message that explains the problem and its solution."
Where on a Deskjet D1420 could an error message possibly appear?
Does it mean this message in /var/cups/error_log?
E [13/May/2021:15:18:53 -0400] [CGI] Unable to create avahi client: Resource 
temporarily unavailable
E [13/May/2021:15:18:53 -0400] [cups-deviced] PID 2094 (dnssd) stopped with 
status 1!

Would the presence or absence of whatever
avahi is cause the printer to complain?

The printer used to print.
The hardware connection has not changed in years.

Any ideas?
