The problems come when you try to manipulate the files - add
printer-specific feature commands, do page imposition, etc.

Since CUPS does that with EVERY print file, the results for non-
conforming files are undefined.  IOW, while a particular application
or file may print consistently one way, we don't guarantee the
behavior of those print jobs on all printers when they do not conform
to the DSC.
