Concerned about scrolling side to side?
To solve the problem on your computer, go to the settings panel on your computer, and set the resolution to 1024x768, or higher, and that should solve the problem.
Web sites are designed for computers, not printers, so if you want to print most present web sites, you will have to set your printer on landscape to be able to print the whole screen.
When printing, the printout may not always look like the screen, as code is telling the computer where to place pictures and text directly, and printers cannot read code. Specific printer margins will also have an effect on printouts, especially page breaks.
