CUPS was initially called "The Common UNIX Printing System". This name was shortened to just "CUPS" beginning with CUPS 1.4 due to legal concerns with the UNIX trademark.<ref name="CUPSName">{{cite web|date=April 24, 2012|title=CUPS Presentation at 2012 Open Printing Summit|url=http://ftp.pwg.org/pub/pwg/liaison/openprinting/presentations/cups-plenary-april-12.pdf|url-status=live|archive-url=https://web.archive.org/web/20170214175407/http://ftp.pwg.org/pub/pwg/liaison/openprinting/presentations/cups-plenary-april-12.pdf|archive-date=February 14, 2017|df=mdy-all}}</ref> CUPS was quickly adopted as the default printing system for most [[Linux distribution]]s.
