Printing a web page might be very frustrating. Sometimes the page you want to print is full of ads banners or doesn’t fit well on paper size (A4 or letter).
The solution is to use a bookmarklet created by Steve Clay called MyPage.
The MyPage bookmarklet is described in this page.
Once installed, after activation the bookmarklet allows to remove area on a web page by clicking. See the tutorial on the MyPage presentation.
This bookmarklet is very convenient to remove irrelevant area in a web page before printing.
