Hi,sometimes the output of PS(set_plot,'ps') is not the same as what I see
on the screen(set_plot,'win'), for example, the text may has different
position and size. How to solve the problem? Would you please tell me the
plot format you used for print? Apprieciate your answers. Tom

I use Liam's pson and psoff for this all the time. Nice and simple to use.

People have written whole book chapters about this problem!
That said, you might get quick satisfaction with the PSON and PSOFF
procedures I wrote as examples for my book. You can get them as part of
the sample programs package at
http://www.gumley.com/PIP/About_Book.html
Once you have these two procedures installed, you can do something like
this:
;- Create a test plot in a graphics window
window, /free
x = findgen(200) * 0.1
plot, x, sin(x), title='A Test Plot'
;- Start PostScript output
pson, filename='testplot.ps'
;- Redo the plot
plot, x, sin(x), title='A Test Plot'
;- End PostScript output
psoff
The PostScript file testplot.ps should contain a plot with the same
aspect ratio and text size as the version in the graphics window. If you
want to know the details of how PSON and PSOFF work, get yourself a copy
of "Practical IDL Programming".
Cheers,
Liam.
