Something they don't advertise, and may or may not be just a rumor (I haven't been diligent about looking into it, it's still on my giant to-do list): there are identifying markings that may be printed with every page on virtually all printers. This allows them to trace any paper that was printed to the printer used and at least it's point of sale, if not right to the doorstep of the guy who bought it. That would be bad if printing postage for drug shipments, methinks. Just an FYI.
