Let me put in a good word for these little utility programs that I got from Liam's
library. I use 'em a lot and they're great for quick and easy PS output. In a lot of cases
I just want to change the size of a plot so it looks better on a printed page. With
PSON/OFF all I do is change the onscreen graphics window to how I want the plot to
look/be-sized, invoke PSON, replot, PSOFF, and it's done. No more stuffing around with
SET_PLOT and DEVICE.

You may also be interested in the PSON and PSOFF utilities I developed for
my book. PSON sets up the PostScript page with the same aspect ratio as the
current graphics window, and sizes the plot to fit inside the drawable area
of the page. A range of pages sizes (Letter, Legal, A4, etc.) are
selectable. For example:
;- Create a plot in a graphics window
window, /free
plot, indgen(10) * 10000.0
;- Reproduce the plot in PostScript landscape mode on A4 paper
pson, /landscape, paper='A4', filename='test.ps'
plot, indgen(10) * 10000.0
psoff
The plot in the PostScript file will have the same aspect ratio as it does
in the graphics window. I find these utilities much easier to use than the
usual SET_PLOT and DEVICE commands. You can find PSON and PSOFF in my
example program library at

Huh!? Could you just show us the part of the code
you are using to produce your PostScript file. :-)
When I Plot, Findgen(10000) I get the same kind of output
on the display and in the PostScript file, using either
vector fonts or hardware fonts (font=0). Are you using
some particular kind of font?
Cheers,
David

Have you tried TrueType fonts? For example:
set_plot, 'PS'
device, set_font='Helvetica', /tt_font
plot, indgen(10) * 10000.0, font=1
device, /close_file

Liam.
