I guess that's why TransScript sells so well then :-)

The standard trick is to assume that a postscript file will begin with
at least a %! comment. Some go as far as expecting %!PS-Adobe-## but
one should really only do that if one is doing explicit processing
based on the Adobe Structuring Conventions.

Then you either insert an extra leading newline to defeat the filter,
or your run "enscript" or clones thereof or "a2ps" on it yourself. An
alternative is to have seperate queues that "always filter" or "never
filter" but really, if you have *users* on your system, you don't want
them to be able to print postscript as raw text without trying
*really* hard :-)

Read the printcap man page; there's a single boolean token for it,
last I checked (which I'll admit was 4.3BSD for VAXen but it's not
like printcap is a hot research topic :-)
