CUPS Common Print Dialog Backend

This repository hosts the code for the CUPS Common Print Dialog Backend. This backend manages and provides information about CUPS and IPP printing destinations to the printing dialog.

Background

The Common Print Dialog Backends project aims to move the responsability on the part of the print dialog which communicates with the print system away from the GUI toolkit/app developers to the print system's developers and also to bring all print technologies available to the user (CUPS, cloud printing services, ...) into all application's print dialogs.

Dependencies

  • cpdb-libs: Version >= 2.0.0 (or GIT Master)

  • CUPS: Version >= 2.2 sudo apt install cups libcups2-dev

  • GLIB 2.0: sudo apt install libglib2.0-dev

Build and installation

$ ./autogen.sh
$ ./configure
$ make
$ sudo make install

If you are updating from an older version, please kill the old version of the backend:

$ sudo killall cups

This way the next time when a print dialog is opened the new version of the backend is started.

Following the development and updating

The current source code you find on the OpenPrinting GitHub.

Running

The backend is auto-activated when a frontend (like a CPDB-supporting print dialog or the example frontend demo/print_frontend of cpdb-libs) is started, so there is no need to run it explicitly.

However, if you wish to see the debug statements in the backend code, you can run /usr/local/lib/print-backends/cups

NOTE: The communication protocol between frontends and backends has changed (Job data streaming via domain socket, printer list filteringvia D-Bus methods). Therefore use this backend only with frontends based on cpdb-libs of at least version 2.0b6.
