Got it. Time to write a filter....

Completed successfully.

The Mac is sending pdf, from what I have read the printer is doubling up the rotation by sending a postscript rotate command to the printer (two rotations).
The que ppd looks like a good place for prefilters but I need  a ps post filter.

Where do I tell the cups system to insert a post filter?
Shouldn't a simple script to change any ps reference from landscape to portrait 'patch' the problem?

Day one at this, am I going down the wrong path?
