Update (09/06/2014): Now this tool can also be used to extract the selected pages (only in Acrobat, of course). You select the pages just like before (using the added check-boxes) and then click a menu item that tool adds under Tools - Add-On Tools, and the selected pages are extracted to a new file.

Also improved is the mechanism that prints out the pages. If Acrobat or Reader XI are used all of the pages will be printed out in a SINGLE print command, not one by one. And if an older version is used the tool will attempt to print out the pages in as few print commands as possible by grouping the selected pages into ranges.

Sometimes you want to allow the reader of your file to easily select which pages they want to print out of it.
With this script you can automatically add a check-box to each page of your file, as well as a Print Selected Pages button.
The user can then simply tick the pages they want to print and then print them all with a single click.

After printing the user can reset the check-boxes, if they wish:
