[cups.general] MacOS 10.7 & client.conf

[Michael Sweet]

Helge,

The application sandbox profiles are not imposed on cupsd (which *does* sandbox filters and backends, but with a more permissive kind that allows for network access) but rather on the applications themselves, and each application tells the OS what kinds of things it needs to do.

Since Text Edit and other non-network applications don't say they need network access, the sandboxing specifically doesn't allow network access...

The sandbox *does* allow communication with the local cupsd, so it is mainly an issue of adding the queues you are interested in.  Bonjour (both local and wide-area through traditional DNS servers) allows you to see printers you haven't yet added and add them from the print dialog, you just can't talk to them directly (just through cupsd).

Using BrowsePoll in cupsd.conf *may* work, but CUPS browsing is deprecated and I don't like to recommend it anymore...
