Print document, spooler crashes. Document cannot be removed from queue because spooler is not running.
Reboot computer. Document in queue immediately tries to print, spooler crashes.
Solution: Turn off printer, reboot computer. Delete document from queue. Turn on printer.
You'd think that critical infrastructure like the print spooler would be a bit more robust. Or at least be able to detect that it is repeatedly crashing on a single document and ask the user if they'd like to cancel the offending print job. Or make cancelling print jobs not dependent on the spooler service. Also, apparently user permission to manage print queues does not extend to restarting the print service itself.
Aside: You know how when you say a word over and over it starts to sound funny? Apparently Chrome gets the same way too... it didn't start highlighting "spooler" as a misspelled word until I wrote it about 5 times.
