If the 2nd option is selected (crop) then when I print to the 'tabloid' MediaName and the General Media Size is set to 'letter' the tabloid pdf document is cropped.

It always wants to print on the default size that is set under the General heading in the CUPS printer configuration screen.  As I mentioned this does work for other printers, but not for the Xerox 7750.

Hi,

I was able to get a sample control file, I should have a sample data file tomorrow - it appears that both these files have many non-printable characters in them.
Here is the sample control file (with the non-printable characters removed):
