        $('#mainCont').append(graphWrapper);

I came across a solution for this annoying problem. It was actually linked in another answer to a similar issue on StackOverflow.

The direct link to the solution is here.

I have verified it and it works great. Here are the samples I built to show the hack in action. Open the samples in appropriate version of IE (7, 8 or 9 with the browser mode set to IE7 or IE8) then try print preview and you will see the difference:

A sample with the hack.
A sample without the hack.

PS: Please do not hesitate to give @user1065335 a +1, I did, for finding it, good job mate :)

Well we were using a Mordernizr for the HTML5 support in our site. and to optimize the code instead of taking the entire mordernizr file. We created a custom Mordernizr file.

That is wat where the issue was, we forgot to include the PRINTSHIV checkbox from there, thats wat screwed it up :)

well this is the link which worked and resolved this issue.

This was on hold for a long time. Just got it resolved yesterday and am so Glad.

Also like to thank BORO for his answer, that works to incase u dont user Mordernizr.

CUSTOM MORDERNIZR which worked
