printing any file give "Unsupported format 'the/format'"

[magilus]

Binary package hint: cupsys

See the Debian bug report this bug is linked to for more information.

I just upgraded a Edgy install to Feisty, and exactly this issue appeard to me. I could not print anything, CUPS said: "Unsupported format 'application/postscript'!" when trying to print a test page.

My workaround was to create /etc/cups/pstoraster.convs with the following content:

application/vnd.cups-postscript application/vnd.cups-raster 100 pstoraster

After a cups restart, everything worked smoothly again.

This is a bug in the gs-esp package. Since /etc/cups/pstoraster.convs is marked as a configuration file it doesn't get replaced on dist-upgrading.
You probably did one or several dist-upgrades from previous versions of Ubuntu and are still stuck with the pstoraster.convs from the first Ubuntu version you installed.

These commands should solve your problem and install the latest pstoraster.convs:

$ sudo dpkg --purge --force-all gs-esp
$ sudo apt-get install gs-esp

Can you provide the output of the printingbug info script for some basic information about your printing setup. The printing bug info script can be found here: https://wiki.ubuntu.com/PrintingBugInfoScript.
