I remember, a MFC7820 Laserprinter is used in one customers office via

I thought I make only a little fault, I wanted to print to the HL5250 
postscript printer directly with less effort. But it seem to be not very 
easy to bypass, so I print using CUPS backend, okay! Thats all what I 
wanted to know.
