| But there's an even more general way to do more than one thing inside
| an "if": the "progn" form.  It simply does a bunch of things one after
| the other:

And of course, there is cond:

(cond
 ((eq window-system 'w32)
  (setq ps-printer-name t)
  (setq ps-lpr-command "c:/Program Files/Ghostgum/gsview/gsprint.exe"))
 ((eq window-system nil)
  (setq ps-printer-name t)
  (setq ps-lpr-command "/cygdrive/c/Program 
Files/Ghostgum/gsview/gsprint.exe")))

And then there are when and unless in the cl package:

(require 'cl)
(when (eq window-system 'w32)
  (setq ps-printer-name t)
  (setq ps-lpr-command "c:/Program Files/Ghostgum/gsview/gsprint.exe"))

(unless window-system
  (setq ps-printer-name t)
  (setq ps-lpr-command "/cygdrive/c/Program Files/Ghostgum/gsview/gsprint.exe"))
