In addition to the benefits for the user, this style sheet reduces the number of pages printed, and therefore indirectly minimizes the website’s ecological footprint. It should be as streamlined as possible and employ an ink-light typeface e.g. Century Gothic. Also consider hiding the header, footer, menu and sidebar, as well as deleting all images except those needed for content.

Resize and optimize images outside of the website because a web server is not designed to perform such operations. This saves bandwidth and lightens the load on the processor(s) and RAM.
