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.

The PDF is OK, the MediaBox specifies tabloid size exactly. I'd strongly suggest to 
convert the PDF to a PostScript job by
	pdftops -paper match your_PDF_file your_PS_file
(using the pdtfops utility from the xpdf suire; make sure using a version of 3.0x at least)
and print the PS file. If it then prints on the correct media size, your issue is due to
the restrictions of CUPS' pdftops filter (which seems to support only letter, legal, A4, A3,
and a "universal" format which has dimensions someshere between letter and A4.

If what I suspect s true, you could resort to the "alternate pdftops filter" as I suggested
earlier.
