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.
