Microsoft saves paper and trees by defaulting all of the printers to double-sided printing. Or, at least they purport to. I wonder how many pages and how much ink I've wasted in the three and a half years I've worked here after printing something, going to pick it up, realizing it printed double-sided, recycling that copy, and then printing a single-sided copy.
If I'm printing something, it's either to send to someone (for a rebate or something), to fill out and fax, or it's a single page. I don't want crap printed on both sides. At least the printers don't default to stapling the corners anymore.
