My general assumption behind this is that if you try to print a PDF from Adobe Reader for Linux on the host, it will be converted into Postscript first, then into whatever printer-specific language that may be required: usually PCL 3, PCL5, PCL 6 - or back into PDF.
This conversion from PDF to PS and again into PDF with CUPS is, from my experience, *not* a 1:1 mapping/translation, so the resulting PDF should be a "basic" PDF type with all the trouble-causing fanciness removed (and usually resulting in a significantly larger spool file).
To further back up my own claim here: "Following the reconversion from PDF to PostScript, the file /tmp/colorcir.ps does not match the original file /usr/share/doc/packages/ghostscript/examples/colorcir.ps. However, there should be no visible difference in the printout.", quoted from <http://www.novell.com/documentation/suse91/suselinux-adminguide/html/ch06s06.html#sec:d.ghostscript.postscript>
