  • ?Apple Raster

    • See ?URF

  • Auto Discovery

    • Techniques which lead to automatic discovery of remote, shared ?queues and ?printers on the local network and making them available for printing to.


  • Backend

    • Used for ?printer discovery and sending a document processed by ?CUPS and ?cups-filters to the device after it has been converted to a format understood by the ?printer.


  • CUPS

    • Manages all aspects of printing a document and is at the heart of Debian's default printing system. Subject to continual upstream development.

  • CUPS Error Log

    • A file for diagnosing issues and misbehaviours of the printing system. Logging to the file is done not only by ?CUPS but by other printing processes such as ?cups-filters.

  • cups-browsed

    • A setup tool for ?print queues and ?printers. Comes as a package separate from cups-filters and is essential on Debian 8 (jessie) and 9 (stretch) for automatic discovery and setup of remote ?queues and printers.

  • cupsfilter

    • A diagnostic program included with ?CUPS. Convert a file to a specific format, just as if it had been printed through CUPS. Nothing is sent to the ?printer.


  • Device Uri

    • A Uniform Resource Identifier (URI) is an addressing technology for identifying where to dispatch the file sent by a ?backend. USB and network printers are supported by ?CUPS with various schemes.

  • Driverless Printing

    • Printing using only free, open-standard software and ?filters. No vendor-specific drivers or ?PPDs.


  • ?EWS

    • See ?Embedded Web Server

  • Embedded Web Server

    • An embedded web server resides on the printer in its firmware. It can be used to manipulate how the printer is presented on the network. It may also offer other facilities, such as scanning.

  • ?Error Log

    • See ?CUPS Error Log.

  • ?Everywhere

    • Frequently used to refer to an ?IPP Everywhere printer or to setting up a ?print queue with the ?everywhere model


  • Filter

    • Programs or scripts for converting from one input format to another format that can be printed directly or sent to another filter. Examples are texttopdf, pdftopdf, gstopdf and rastertopwg. Both ?CUPS and ?cupsfilters provide filters for the printing system.




    • Free software exclusively for Hewlett Packard (HP) printing, scanning and faxing devices.


  • IPP

    • The protocol used by ?CUPS for local and network communication between client devices (computers, mobile phones, tablets, laptops etc.) and printers and print servers.

  • ?Internet Printing Protocol

    • See ?IPP

  • ippusbxd

    • Implements ?IPP-over-USB driverless printing (originally only available to a network printer) on a ?suitable USB connected device.




  • lpadmin

    • The fundamental utility for setting up a ?print queue. Used by all other setup programs.



  • Non-free Drivers

    • Quite a few printers only provide vendor-specific non-free software, which is not allowed to be distributed with Debian. Recent printers from such manufacturers falling into this category should be capable of being used with ?driverless printing to avoid this restriction.



  • PDF Centric Workflow

    • All files submitted to a ?queue are first converted to a PDF. After that, the PDF produced by the conversion is processed by pdftopdf before being sent for further processing and then on to the printer via a ?backend.

  • pdftopdf

    • A page management ?filter which is central to the ?PDF centric workflow.

  • PPD

    • A PostScript Printer Description (PPD) file describes the capabilities of the printer. These capabilities are displayed in the ?dialogs of applications and with ?lpoptions and are sent to the ?queue when selected. A PPD file is often referred to as a driver.

  • Printer

    • A peripheral device which communicates with the output of a ?queue to put graphics or text on paper.

  • Print Queue

    • A file to be printed is submitted to a queue, which is managed by ?CUPS. ?cups-filters is involved in processing the file and the output is usually sent to a printer. A single printer ?can be associated with many queues.


  • ?Queue

    • See ?Print Queue


  • RasterView

    • A CUPS, PWG, and Apple raster file viewer.



  • Temporary Print Queue

    • A feature of a client CUPS 2.2.4 and later when remote, shared queues and ?IPP printers are advertised on the network. The ?queue is only brought into existence when it is printed to.

  • texttopdf

    • A ?filter to convert text to PDF. The output is generally sent to the pdftopdf filter for the pages to be managed.


  • URF

    • A raster ?filter format devised by Apple for use with AirPrint-capable ?printers. The acronym appears to have originally stood for Universal Raster Format but it is now known as Apple Raster. ?CUPS converts files to Apple Raster with its rastertopwg filter.


  • Viewers

    • The outputs of some ?filters are viewable with various utilities.
