CUPS (formerly an acronym for Common Unix Printing System, but now with no official expansion) is a modular printing system for Unix-like computer operating systems which allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to the appropriate printer.

CUPS consists of a print spooler and scheduler, a filter system that converts the print data to a format that the printer will understand, and a backend system that sends this data to the print device. CUPS uses the Internet Printing Protocol (IPP) as the basis for managing print jobs and queues. It also provides the traditional command line interfaces for the System V and Berkeley print systems, and provides support for the Berkeley print system's Line Printer Daemon protocol and limited support for the server message block (SMB) protocol. System administrators can configure the device drivers which CUPS supplies by editing text files in Adobe's PostScript Printer Description (PPD) format. There are a number of user interfaces for different platforms that can configure CUPS, and it has a built-in web-based interface. CUPS is free software, provided under the GNU General Public License and GNU Lesser General Public License, Version 2.

Famous quotes containing the word cups:

    What a devil hast thou to do with the time of the day? Unless hours were cups of sack, and minutes capons, and clocks the
    tongues of bawds, and dials the signs of leaping-houses, and the blessed sun himself a fair hot wench in flame-colored
    taffeta, I see no reason why thou shouldst be so superfluous
    to demand the time of the day.
    William Shakespeare (1564–1616)

    When cups went round at close of day
    Is not that how good stories run?
    The gods were sitting at the board
    In their great house at Slievenamon.
    They sang a drowsy song, or snored,
    For all were full of wine and meat.
    William Butler Yeats (1865–1939)

    Call the roller of big cigars,
    The muscular one, and bid him whip
    In kitchen cups concupiscent curds.
    Wallace Stevens (1879–1955)
