That doesn't mean PS level 2.   (It means version 2 of the DSC
comments, but should make no difference).  That doesn't solve your
problem, I know, but there's not much information in those two lines.

Thanks Aandi for your quick reply. Ok, I don't think it is appropriate to put the entire file here. But this is a larger portion of the header, until it just becomes numbers. I then included the tail end of the file. It doesn't resemble any other PS file I've looked at.

Looks normal enough to me - PostScript is a programming language and
anything goes, pretty much.

I think you have two choices:
- contact the support people for the Unigraphics program, who should
be making files that work. Test it with GhostScript on HP/UX to give a
test they should be absolutely familiar with - most Unix PostScript
probably goes to GhostScript.
- find (or become) a PostScript expert to read the file, line by line,
examining the program for why it is blank (often much harder than
finding an error).

I think the problem is with the coordinates falling below the bottom of the
page and at right of its right margin, at leat that's the problem with the
fragment you posted. Add a "-612 792 translate" before the "0.05 0.05 scale"
and something will show up (not necesarily what is intended to be shown).

David,

If the HPGL output from UG does plot, why not just use that?

My company makes PostScript conversion software, and we have a number of customers who use it for PS files generated from UniGraphics. I can't speak for your plotter, but our software generally handles them without problems. Chances are it's plain Level 1 PostScript by the way, as most technical applications on UNIX output that.

If the problem persists and you need a solution, you could consider trying our ps2vector module (available on HP-UX) to batch convert the UG PS files automatically to HPGL (or to 'our' Level 1 PostScript output) for rendering by your plotter. You're welcome to send me a sample UG PS file for us to have a look at and convert as a test.

Usually you don't get a print if you use white ink on white paper
or your drawing is outside the page or a clipping rectangle.
Both are easy to find out.

In case of "outside drawing":

- set the scales to millimetres at the beginning of the file and save the ctm (use gsave/grestore not to spoil your scales)

- re-define the processes that use moveto and lineto so that they
calculate the x y coords in millimetres, then define/update
x_min y_min x_max y_max with them (using transform, itransform and your saved ctm)

- at the end set the scales to millimeteres, convert x_min etc to strings, and plot them where they are surely visible.
