IDL uses the environment variable IDL_DEVICE to determine the
initial output device. If IDL_DEVICE is set IDL calls set_plot with
the given name. If IDL_DEVICE is not set IDL tries to start with
set_plot, 'X' or set_plot, 'WIN' or some similar device depending
on the operating system.
Note that if you output to PostScript you most likely need to call
DEVICE to pass necessary parameters to the PostScript driver.
Otherwise defaults are used such as portrait orientation, 8.5x11
inch paper, monochrome, filename idl.ps and more.
If you need a setup for European A4 or A3 paper drop me a mail...
