To create a PostScript plot which matches your onscreen plot, try
this.

1. Download the sample programs from "Practical IDL Programming"
http://gumley.com/PIP/Sample_Programs/PIP_programs.zip

2. Create your plot onscreen in a direct graphics window, e.g.
IDL> window, /free
IDL> plot, sin(!pi * 0.1 * findgen(100)), title='My First Plot'

3. Recreate the plot with output directed to PostScript using PSON and
PSOFF, e.g.,
IDL> pson, file='test.ps'
IDL> plot, sin(!pi * 0.1 * findgen(100)), title='My First Plot'
IDL> psoff

You will find that test.ps contains an exact replica of your onscreen
plot. You can also try variations like this:

IDL> pson, file='test.ps', paper='A4', /landscape
IDL> device, /helvetica
IDL> plot, sin(!pi * 0.1 * findgen(100)), title='My First Plot',
font=0
IDL> psoff

This will recreate the plot in landscape orientation on A4 size paper
using the PostScript Helvetica font.

Cheers,
Liam.
