We run linux clients that connect to a central print server. I found
this works:
1) Install cups server on the clients.
2) On clients turn on "Show printers shared by other systems" in web
interface or in /etc/cups/cupsd.conf
# Show shared printers on the local network.
Browsing On
BrowseOrder allow,deny
BrowseAllow all
BrowseLocalProtocols CUPS dnssd
BrowseAddress @LOCAL
BrowseAddress server:631
# *** NOTE I've added an entry that points directly to our main cups server -
to speed up discovery.
3) On clients add a "BrowseAddress server:631" that points directly to
your cups server. Change "server" to addres of your cups server. ( see
above )
4) On clients comment out all entries in /etc/cups/client.conf . This
will force cups to use /var/run/cups/cups.sock on the client.
Generally works because libreoffice doesn't communicate over TCP:631, rather
directly to the local socket and the client<=>server communication is done via
cupsd<=>cupsd:
Client Libreoffice ...
=>local-cups(with browsing on listening on /var/un/cups/cups.sock) ...
=>server:631 browsing cups ...
=>printer.
It uses a bit more RAM on the client to run the cups server but RAM is not as
much of an issue these days.
