Sometimes, the format and layout of a web-page does not help. It can also be written differently or by using java or even flash.
Printing can be helped by two things....
The Browser .. Firefox has a very good pre-print (Print Layout) section one can set up.
The Printer Drivers/Interface. These can help resize, stretch, etc.
Try pressing Control key and the P to see what you get.
If no good, you can capture the screen with the PrtScn button and paste into most Photo programs as a new image file.
