Avahi support for CUPS 1.5.0

Tuesday, August 9th, 2011

The Avahi support for CUPS has been ported to 1.5.0 now.  I’ve updated the git repository (tracking upstream CUPS, as well as having feature branches for Avahi):

Fedora packages for F-16 and rawhide have been built.

More D-Bus goodness in system-config-printer

Friday, July 22nd, 2011

Previously I’ve described the D-Bus activation of dialogs in system-config-printer-1.3.  That D-Bus interface has been extended to help improve GNOME.

Fedora 15 has been released for a little while now, including GNOME 3.  One of the great new features in this release of GNOME is the System Settings window.  It is easily accessed from the system menu in the top right corner of the desktop.

This shows a System Settings window containing an overview of all the various tweakable settings for the system, including personal preferences.  They are shown as icons, such as “Keyboard”, “Background”, “Printers” etc, organised into groups: Personal, Hardware, System, and Other.  Clicking on one of them changes the window so it shows the settings relating to that topic.  So if you click on Printers, you get this:

It’s great to have printer configuration in GNOME, and this interface is nice and simple.  There are a couple of things that it needs to learn to do though.

Using system-config-printer from D-Bus

Wednesday, April 13th, 2011

One of the new features in system-config-printer-1.3 is that various dialogs are can now be invoked using D-Bus.  The details of this are in the file scp-dbus-service.py but here is a summary.

The general idea is that new instances of the New Printer and Printer Properties dialogs, as well as a single instance of the Job Applet, can be requested, and these are given their own object paths.  Each has its own simple interface.

Printing Test Day

Wednesday, March 23rd, 2011

Fedora 15’s Printing Test Day is next week: Tuesday March 29th.

This test day is for testing all aspects of printing, including setting up the printer, sharing printers on the network, and printing jobs.

If you have access to a printer, please come along and help test things out!

Adding a printer to CUPS

Wednesday, February 23rd, 2011

The GNOME 3 printer settings module looks like it will be great. The plan for adding a new printer is deceptively ambitious: the user interface design is that you click “+”, choose a printer device, and then click “Add” and the job is done.

For those unfamiliar with printing, this sounds easy enough. To make the user interface as easy to use as that takes more work than you would think at first glance. It’s the direction I’ve been moving towards in system-config-printer.

Here is a description of the issues involved.
