You didn't mention why you would want to do such a thing.  HPGL has nowhere
near the power of PostScript.  There are no fonts, etc.

Personally I believe that trying to put PostScript onto a HPGL device is a
big step backward.  If you have a SS2, you should have a PostScript printer.

Oh, I'm sorry.  I didn't realize my motives were important.

Well, Vidiot, let's suppose I happen to have an HP pen plotter, for the sake
of argument, that needs HPGL as input.  Also, for laughs, let's suppose I
need to output D-size maps, and not, let's say, pretty PS fonts on 8.5x11
or 11x17 paper.

(Hmm, a problem.  I'll post, and see if I can get some clues from the net 
folks.  Maybe, if I'm real lucky, Vidiot will post, and enlighten me.)

Well, we do, a couple in fact.  Thank you for your obvious concern, though.
Unfortunately, neither of them support D-size output.  I have yet to work
with a PS printer that does.  Imagine that.  Ah, but if I convert our
PostScript to HPGL, then I can use it to drive our HP pen plotter.
Problem solved.

Later.

This must be the F-est of all FAQs.  Read the FAQ posting.

(I believe the stock answer is ghostscript, though the version I have
*always* prints one page per file, not directly directable to the
spooler via stdout.  The results look good, but I wasn't too happy with
the process I had to go through to get it from PS to file to printer.
Fortunately, I've since obtained access to a PS printer.  I've not read
the FAQ recently myself.)

Duh, maybe because he already has a 300 dpi laser printer and hopes
that he can conserve precious landfill space by finding a way to use it
with newer software?

>HPGL has nowhere near the power of PostScript.  There are no fonts, etc.

The PS _language_ is a lot more powerful.  The proper software on a
workstation, however, should be able to produce the same arrangement of
those 300 dpi on an HPGL printer as would a printer with on-board PS.

>big step backward.  If you have a SS2, you should have a PostScript printer.

Down with the categorical imperative!  Given that you feel so strongly
about it, why don't _you_ buy him one? ;-)  BTW, what's a PS cartrige
cost for an HP printer, and what's the lowest/oldest model that can
accept it?  That might be his best answer.

Well, not having read FAQs: He wants HPGL, not HP-PCL! Plotters do not come
as matrix printers - that is until recently, until the invention of
bubble jet plotters :-)

>>You didn't mention why you would want to do such a thing.

One reason I can give you - not the original poster of the question:
One of my programs sorts through tons of data and produces ugly looking
PS output. I've a CAD program, which eats HPGL. That would allow me to
import the data, then edit the final looking of a plot before sending it 
to a PS printer again. MAy be an awful way. May be I should resort to
scissors and glue...

>Down with the categorical imperative!  Given that you feel so strongly

I volunteer to take another one :-)

  Maybe, for one of a thousand reasons or so, he needs to.....

I seem to recall (from a LJ IV manual) that there are commands for
Bezier curves.

But then, you still need the technical refman because the users' manual
doesn't explain how to actually use the commands.

Cheers,
