Well, that's easy enough:

    (setq printer-name "//BREATH-000/Randy's HP 1200")

    ;; must set printer name before issuing print command!
    (if (eq window-system 'w32)
        (setq ps-printer-name t
              ps-lpr-command "c:/Program Files/Ghostgum/gsview/gsprint.exe")
      (setq ps-printer-name t
            ps-lpr-command "/cygdrive/c/Program 

That's because "setq" lets you set any number of variables at once.

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:

    (if (furryp critter)

        ;; yup, furry
          (pet critter)
          (comb-fur critter))

      ;; no fur
        (apply 'sunscreen critter)
        (search-for-tattoos critter)))


And by the way -- I haven't checked to see if this is the case, but I
suspect you can use "c:/Program Files/Ghostgum/gsview/gsprint.exe" for
both Cygwin _and_ non-cygwin versions.  Cygwin programs in general do
the right thing with file names that start with a drive letter and
