Hi,

The trays are installed as you mention with Tabloid and Letter trays set up.
The control file of the pdf that works (printed with the Mac app - Preview) contains a line MediaType AutoSelect - I think this comes from the Xerox PPD file.  I have not found how I might force set this through the IPP protocol. Can I?
