Print page-breaks don't work

[john-gilmer]

I have a webpage that has a gridster area where the user can put in dozens of small charts. If there are enough charts for them to spill onto a second page, I would like the page break in the printed pages to not be right through the middle of the charts. But the page break is right in the middle, and the charts aren't even displayed properly in the printout. I have tried adding I have tried using CSS like page-break-inside with the widgets, but it doesn't work. I am using Internet Explorer 11. I am attaching a PDF of the printout. Thanks for any advice you can give.
