Offline produce page to print from web application

I have a web application and need to print some custom auto generated pages. What I want to be able to do is to have a button and when I press it : 1) the automatically generate a page which will not be displayed at all on screen and after that 2) to send that page directly to a printer that is defined on that system.

What I thought to do, is : the print button to send an SQL query with all needed data to a database and then create a static application that will work like a print spooler, to constantly poll the database for new "printing requests" and then send them to a defined printer.

Can you please suggest of any simpler and more direct solution ?

Thank you in advance.
