Useless historical UNIX facts #1

back in the good old times of line printers, printers were able to report certain errors back to UNIX. One of these was "/dev/lp0 on fire".

I myself, frequently rant about printers, but never flamed about a printer on fire (no pun intended). Back then, everything was more dangerous than it is today - even printers. Makes me wonder what Sysadmins did when this error came up?

For reference:
