[cups] CUPS + VPN

[Alex Korobkin]

I have an if-up.d hook script for that. It tries to guess if you're
connected to the enterprise network and changes ServerName to printserver
or localhost in client.conf. It doesn't restart CUPS though, I'm not sure
why you have to restart CUPS in your environment.

This approach doesn't solve all the problems, though, because many Linux
apps don't re-read the list of printers after they have already started.

LibreOffice or Firefox, for example. If you have them open when moving from
home to work, or connecting to VPN, you will see the same list of printers
all the time until you close and reopen the application.
