CentOS - Oct 2018 - Cups freeze when remote server is unavailable

Hi,

I have a setup problem with cups on my CentOS7 laptop.

In client.conf If have set the cups server FDQN used at work

ServerName servprint.lmy.lab.fr


But when I'm at home if I do not comment this line with:

# ServerName servprint.lmy.lab.fr


cups freeze as soon as I try to print something on my local home printer
as the remote server is unreachable.

This seams to be an old 2012 bug (see
https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1050422) but I'm
unable to find any work around 6 years later!

My cups in CentOS7 is cups-1.6.3-35.el7.x86_64


Any idea ?

I don't see that this is a bug.

In client.conf you're telling it which server to use, exclusively. 
You're not
adding remote printers, you're telling it which CUPS server to talk to
everytime you use CUPS clients commands.  You don't even need to run a local
CUPS server if you configure it like this.

If you want a machine to work at both ends, I'd suggest you don't do
this, and
instead run a local CUPS server, and add remote printers to that local server.

Hi John

thanks for your quick reply. If it is not a bug, as I was reading on the
web, it is some misunderstanding from me.
Running cups 1.4.2 (CentOS6) I was using the "BrowsePoll" directive in
cupsd.conf. So the printers were automatically known from the central
server of the lab. And home printers were working fine with this setup too.
In CentOS7, with cups 1.6.3, this directive does not exist any more and
reading the doc I had understood that it was replaced by the client.conf
file. Reading your answer suggest it is not true.

So could you tell me or suggest reading on the right manner to reproduce
my previous centos6 setup ?

Sorry for this newbie question, I'm not very familiar with cups setup.

Patrick
