[cups] Lexmark T520 printing PJL commands

[Pförtsch, Franz]

Hello Leo,

try to use a different postscript ppd.

As a rule of thumb start with the original vendor ppd.
The minimum ppd, try to use the apple laserwriter ppd.

Regards
Franz

Further investigation using sub sbiffing leads me to believe that cups-1.4.6 never used pcl/pjl commands, but cups-1.6.3 does.
It appears that my printer does not understand (all) the commands it is getting from cups.

Is there a way to disable pcl/pjl for this printer?
