Sure, this is still bugging me and I'm eagerly awaiting a new release or
some kind of explaination how to solve this.
I know Patrick had some big project he was working on, but I belive he
said it was comming to an end. And after that he would continue the work
with LPRng... But, I haven't seen too much from him lately so.. I don't
know.. I just hope.
Max!

> Now, take a look at those filter command lines. In version 3.6.26 there is
