I have seen NOFORN printed in all seriousness at the top of a report cover. Apparently that is pentagon-speak for "no foreign distribution".
About a decade ago I went with cash in hand to several data recovery companies and asked them to recover some wiped files on a working disk. Distructive techniques were allowed, and the budget would have paid for some elaborate processes. Several first-level telephone answering folks said "sure, we can do it", but when I told the same story to the next level no one was willing to try. There is, of course, that old report claiming that there is enough information physically present in a multiply erased bit position to permit recovery. Maybe the intelligence agencies can do it, but I have heard of no verified case where they - or anyone else - actually did.

I kept getting a message that I should cancel, change driver settings to the sheet feeder instead of the paper cassette (which won't feed tall sheets) and try again, but I had already made that change. I finally noticed the printer lights indicating that something was overriding my selection, then setting it back after provoking the error message. Driver or application? I tried printing the same file to the same sheets with the same driver settings through Open Office Writer, and it worked flawlessly. That puts OO in a different role from the catch-up you normally hear about, methinks.
