ps-selected-pages

ps-selected-pages is a variable defined in `ps-print.el'.
Its value is

nil

Documentation:
Specify which pages to print.

If nil, print all pages.

If a list, the lists element may be an integer or a cons cell (FROM . TO)
designating FROM page to TO page; any invalid element is ignored, that is, an
integer lesser than one or if FROM is greater than TO.

Otherwise, it's treated as nil.

After ps-print processing `ps-selected-pages' is set to nil. But the
latest `ps-selected-pages' is saved in `ps-last-selected-pages' (which
see). So you can restore the latest selected pages by using
`ps-last-selected-pages' or with the `ps-restore-selected-pages'
command (which see).

See also `ps-even-or-odd-pages'.

You can customize this variable.

This variable was introduced, or its default value was changed, in version 20 of Emacs.
