Is there a way to print out a mirror image of a postscript file?
Someone wants to test some artwork for a printed circuit board,
and we need to get a mirror image of what the CAD package
generated.  THe program is retarded so it can't reverse the
image itself.

In the red book, there is a reference to MirrorPrint under 
setpagedevice; but apparently it is hardware dependent.
Does MirrorPrint work for an Apple II NT?  Trying to find
docs around here is really interesting.

Any hel p appreciated.  
Thanks

Have you tried inserting

	[-1 0 0 1 612 0] concat

as the first action on the page?

One simple way to do this is to put the following code at the top
of your file:
  612 0 translate
  -1 1 scale

This will fail on multi-page jobs or if your file has "initgraphics"
or certain other operators, but it is so simple it is worth a try.
It also presumes you want to flip horizontally, and your paper size
is 612 units wide (i.e. letter or legal, but not tabloid).

This key is both device-specific and Level 2-specific. Sorry!
