There's been a bug in my system for at least two years and I still don't understand it. Sometimes, maybe every few weeks, a document will not print. The light won't start flashing on the printer. Nothing happens.

However, this is easily fixable by unplugging the printer USB cable from my PowerBook's USB port, and then plugging it back in. Immediately, the printer activates and everything is fine.

I have no idea why this happens. And nothing is being rebooted, although there is probably some kind of reset happening with the USB port. Who knows?

It may have to do with applications that are open, but it's not worth diving into complicated tests, since I have a proven solution to this problem.

I think with any operating system, if you have solid workarounds for nuisance bugs, you're doing well. That's why I'm still using Mac OS 10.2.8. Upgrading to 10.3 or 10.4 would surely bring an entirely new set of hassles. 10.4 looks cool but doesn't have anything compelling enough to justify the switch, and its performance on my 667Mhz/512MB machine would probably be mediocre.
