It is.
Here is the printers.conf from the remote machine:
--------------------------------------
# Printer configuration file for CUPS v1.4rc1

And here is printers.conf for the laptop:

I cannot get rid of the AuthInfoRequired line;
if I delete it, it just re-appears.

Any enlightenment more than gratefully received.


I attach cupds.conf for two machines below.
They were created by CUPS web interface,
and seem perfectly standard to me.

I thought the problem might be due to using hp-setup,
but I have yum-removed this,
and also re-installed cups on both machines,
after deleting all cups files I could find.
But all this had no effect; the outcome is the same.
