No matter how much talk we've heard the "paperless office," fax machines, though little used, are still taking up space.

Why? In part it is because electronic signature technology, as pioneered by Adobe and others, still has yet to meet the critical mass needed to replace legal concerns. Most electronic fax processes require fax modems, which, in that special logic of the Internet age, aren't needed because everyone sends e-mail. (And everyone sends e-mail because no one has fax modems anymore.) Add in a dash of perceived "we might really need it someday" and feature sets such as plain paper printers and scanners, and we'll undoubtedly be stuck replacing thermal paper rolls for ages to come.
