The
postscript option forces the printer to treat all data sent to it as Postscript. It does this by prepending the characters
%! at the beginning of the first line of each job. It is normally used with PCs that insert a
^D (control-D or "end-of-file mark) in front of the first line of a PostScript file. It will not, obviously, turn a non-PostScript printer into a PostScript one. The default value of this options is
no. You can override it as follows:
[deskjet]
postscript = yes
