Just so I better understand what has to be done, how many sets of *different* 67 page files have to be done this way?
To me, there has to be a script that just does "print, pages 105 ; print, pages 6 to page 13 ; print, pages 14 to page 21 ; print, pages 21 to 67".
Int other words, one (clunky?) way to do it is mimic doing it yourself manually. For example those "repeat action" macro programs would do it, and you just run it once per file.
But if you had a whole army of 67 page files to do this on, you'd need another step, some kind of loop to select each one, then do that above.
