How to set print margins via web page?

Is it possible to manipulate printer margin settings via controls/code within a web page?
I have a web-based app which requires users to print web pages frequently. In order to print the full content on an 8.5×11 page requires use of 0.25″ margins on the left & right side. Most web browsers don’t use 0.25″ as their default, so I’d like to override the default and use the desired (0.25″) setting.

Please give your advice & direction on how I could approach this problem.

Thanks,
Pete
