The command-line switch to `pr'.  They are listed in the `pr's man
page, and you already told here that you understood what switches you
want, so I'm puzzled why you cannot continue.

If you want to invoke `pr' like this:

   pr -x foo -y bar

then the value of lpr-headers-switches should be the list

   ("-x" "foo" "-y" "bar")

The doc string of lpr-headers-switches says that it is a list of
strings.
