@af279435 @ac91e25a caveat: I know what the PC Load Letter message was about. Absolute PITA.
@d4b81373 @af279435 PJL over Ethernet used to allow you to send custom messages to the display on HP printers, might still do, so you could send random weirdness to any printer you could contact via network.
@af279435 @ac91e25a lp0 on fire was far better though.
