Now, after clicking custom action, a stateless form will be opened and there is a drop down to 

list the pages which need to be printed and allow user select page and click "generate " button ,

then page will display in new window and the page itself have a button to"print" and "pdf".

these buttons are options given by creator for pages 

Now,I want to generate all pages into pdf format and print-out in a single custom action click.

Is it possible?
