Once you change the plot device (set_plot), it will stay like that until
you change it back (or restart IDL, where the default device is used).
The usual procedure for using the PS device is
old_plot = !d.name ;; stores the current device in a variable,
;; either 'win' or 'x' depending on your platform
set_plot, 'ps'
device, ... ;; configure PS device
plot, ... ;; plot whatever you want
device, /close
set_plot, old_plot ;; set graphics device back to default,
;; 'win' or 'x'
Often people also store and later restore !p.font and other graphics
device settings.
