All printing controls seems to have disappeared from the Gimp !
[nim@ulysse ~]$ rpm -q gimp
Printing in gimp is provided by the gimp-print-plugin package. Is it
installed and does it verify correctly? Did you upgrade anything lately?
Argh! I did remember to check I had gimp-print packages installed, but
it seems gimp-print-pluggin was not part of those.
So it's probably a yum/apt upgrade that forgot to add it. I'm sorry I
bothered you with this.
