Files containing device-specific commands need to be submitted using
the application/vnd.cups-postscript document-format value.  Otherwise
we treat the file as device-independent PostScript, which has
DIFFERENT rules to follow.

Specifically, if you have an application that wants to produce a
document that overrides the options the user has specified, it should
use %%IncludeFeature or %cupsJobTicket instead of %%Begin/EndFeature
to a) allow CUPS to know that it should apply those options instead
and b) allow CUPS to insert the proper PostScript commands since you
most likely have not done so.

We do our best to not override %%Begin/EndFeature commands, however
because the rules for embedding those things are not well-defined
(i.e. no custom page size support, no support for copies, no ordering
requirements, etc.) bad things can happen, and every "workaround" you
come up with can cause problems.  IMHO, we have only improved our
track record for such things, since before it was possible to have
jobs that would not even print.
