CUPS is the standards-based, open source printing system developed by Apple Inc. for macOS® and other UNIX®-like operating systems. CUPS uses the Internet Printing Protocol (IPP) to support printing to local and network printers.
We periodically deprecate functionality that either is no longer necessary or prevents us from improving CUPS. Deprecated functionality continues to work, often for years, as we help users and developers migrate away from it.
