Export HTML/CSS flyers as image or pdf to print

[zidrave]

I'm creating a web based flyer designer for dog walkers to customize flyers to print off. It's very basic and uses jQuery to change the contents/text of a DIV to what they want on the flyer...My problem is how to let them print the flyers. Ideally, they want to choose between 2 or 4 flyers per A4 page. Or to export as pdf or image to take to a printer. I've looked into exporting html/css as a PDF or image but can't seem to find anything that suits the situation. Any help is appreciated.Thanks
