This is an easy project for some one who has done this kind of work before.
We like to do silent print of pdf in our java / jsp / jee spring web application.
So when a user clicks on a link of the pdf document then instead of seeing / viewing /
reading the pdf it is sent directly to the printer and printer dialogue box opens up
with default printer selected.
It should work in all browsers... Let us know if issues....
If using 3rd part libraries.... explain licensing.
