Hi,

seems no easy way to solve your question. Which is an
inconvenience AFAIS. For the moment here a possible
proceeding relying at the tooltip shown:

From to the source-code directory,

with M-x grep-find and the command

find . -type f -name "*.el" -print0 | xargs -0 -e grep -nH -e "Print region between mark"

it displays

./lisp/menu-bar.el:125:	      :help ,(purecopy "Print region between mark and current position")))

with RET at the link the source is shown:

(define-key menu-bar-file-menu [print-region]
  `(menu-item ,(purecopy "Print Region") print-region
	      :enable mark-active
	      :help ,(purecopy "Print region between mark and current position")))

From there I guess "print-region" is the command looked for...

HTH
