I did some more testing:

All the CreateIPPPrinterQueues lines were commented out but the line
"CreateRemoteCUPSPrinterQueues No" was uncommented. cups-browsed was
removed (the .conf file is left on the system) and cups-daemon purged.
Both packages were then reinstalled. We expect 'lpstat-a' to show "no
destinations added", which it does.

"CreateIPPPrinterQueues AppleRaster" was uncommented and cups-browsed
restarted. The ENVY IPP printer is now the only queue known to the
system.

Running neither 'systemctl restart cups' nor 'logrotate -f' causes the
printer to be deleted. Looks good.

"CreateRemoteCUPSPrinterQueues No" was now commented and cups-browsed
restarted. Four remote print queues are now discovered. Now we are back
to the subject of this report; the ENVY disappears after the restarting
of cups or the running of 'logrotate -f'.
