Is it OK to link to Print-format pages?

Occasionally, posted URLs link directly to pages intended for printable output, excluding advertisements, links to other features of the site, and other browser-oriented niceties.

On one hand, it's true that nobody much likes ads, and multi-page articles are annoying.

On the other hand, the folks that are actually creating the content need their ad revenue to stay in business, and from an artistic point of view, it seems proper to let them display content as they wish.

Should submissions link to the "native" page, or is it OK to link directly to print-formatted pages?
