There is no way to set a paper size in PostScript. You can request a
specific paper size and you can query the size of the print area when
the printer is directly attached to the computer. The application
program (IDL in this case) is responsible for generating the
necessary instructions to fit the plot onto the page. A PostScript
printer is not allowed to scale or rotate the page on its own to
make it fit! This is left to the device driver.

Here is what is contained in IDL Help:
Feature Value
File idl.ps
Mode Portrait, non-encapsulated, no color
Horizontal offset 3/4 in.
Vertical offset 5 in.
Width 7 in.
Height 5 in.
Scale factor 1.0
Font size 12 points
Font Helvetica
# Bits / Image Pixel 4
Table 3.12 Default PostScript Driver Settings

Hmmm well, it may work, but...
Older versions of IDL contained a procedure called
phaser.pro to correctly setup for a Tektronix Phaser
printer. Acutally you have a lot of parameters to
define, esp. when you want to generate both portrait
and landscape output.
I adapted the old Phaser.pro for our Tek Phaser IIIpxi
which can handle both A3 and A4 and the similar US
formats. The essence of my phaser3.pro is:
; $Id: phaser.pro,v 1.2 1993/04/02 19:43:31 Ha THD $
pro phaser3, medium=medium, landscape=landscape, portrait=portrait, $
filename=filename
