## cups-pk-helper
cups-pk-helper is a [[PolicyKit|Software/PolicyKit]] helper to configure [[cups|http://www.cups.org/]] with fine-grained privileges.
For example, it's possible to let users enable/disable printers without requiring a password, while still requiring a password for editing printer settings.
To make it easy to integrate cups-pk-helper in [[system-config-printer|http://cyberelk.net/tim/software/system-config-printer/]], the D-Bus API is based to a large extent on the [[pycups|http://cyberelk.net/tim/software/pycups/]] one.
### Development
The development occurs in git, in the [[cups-pk-helper|http://cgit.freedesktop.org/cups-pk-helper/]] repository. Bugs should be reported in [[Bugzilla|https://bugs.freedesktop.org/enter_bug.cgi?product=cups-pk-helper]].
Translations should be uploaded to [[Transifex|https://www.transifex.com/projects/p/cups-pk-helper/]].
