@section Printing and MS-DOS
Printing commands, such as @code{lpr-buffer} (@pxref{Hardcopy}) and
-@code{ps-print-buffer} (@pxref{Postscript}) can work in MS-DOS and
+@code{ps-print-buffer} (@pxref{PostScript}) can work in MS-DOS and
MS-Windows by sending the output to one of the printer ports, if a
Unix-style @code{lpr} program is unavailable. This behaviour is
controlled by the same variables that control printing with @code{lpr}
-on Unix (@pxref{Hardcopy}, @pxref{Postscript Variables}), but the

defaults for these variables on MS-DOS and MS-Windows are not the same
as the defaults on Unix.
