Not able to print the whole HTML document

I'm not able to print the whole HTML document for my [1] website. The site is making use of a customized printing CSS.

Don't know why but it gets cut off at page 8-9 when printing. It evens prints more information if printing is switched from Portrait to Landscape.

Also, if i enable Print emulation under rendering option on Google Chrome Developer Tools. I also tried printing to PDF using Mozilla Firefox and other web browsers but nothing improved.
