CUPS reaches version 1.6.0!

CUPS is the standards-based, open source printing system developed by Apple Inc. for Mac OS® X and other UNIX®-like operating systems.

We Linux users have been using CUPS for a long time now, and although some replacing works have already begun for obvious reasons, CUPS is still a very important and useful tool for every one of us.

CUPS currently offers drivers for 1249 printers and you can search yours to see if any drivers are available.

As this is a stable version I suggest the update to everyone, but keep in mind that the first bugfix releases will come out in 6-8 weeks.
