[Pkg-cups-devel] Bug#660420: cups: Possibly NO postscript printers work anymore

Hi Jan,

Do you have Postscript-printers? As said, I have no problem printing to 
a PCL5e printer, apart from the same error-message, but the printouts 
are ok.

And for the not readable cupsd.conf:

mschmitt at adrastea:~$ ls -l /etc/cups/cupsd.conf
-rw-r----- 1 root lp 3437 Nov 12 17:42 /etc/cups/cupsd.conf

My useraccount is in the lpadmin group but NOT in the lp group and I do 
not report bugs as root either but cups can read the config file as I 
can see it through the cups webfrontend fine. So here it goes, directly 
copied from the webfrontend:

Afaik the cupsd.conf once was owned by lpadmin but I am not sure. 
Anyway, config seems ok and as said printing works as long as I do not 
try to print to one of the kyocera (postscript) printers.

About reducing the severity of the bug... yes but only if not ALL 
postscript printers are affacted! I am sorry, but I just don't have 
hundreds of postscript printers only two and both do not work anymore, 
even after deleting and readding them. Sure, maybe there is something 
fishy about the postscript language kyocera printers speak... but I 
guess as it worked ok for years before the upgrade, it may not be very 
likely the cause.
