Hp IIIp error code 55

My old Hp IIIP printer has started giving me a error 55 / 79-09ae service error.How can I fix it. Thank you!
Hi. Error 55 is an internal communication error. The 79 extension points to software, drivers, I/O cards, or a plug-in card or module. Turn the printer off. Unplug any font modules from the printer, and turn it back on. If the error persists, cycle power again, remove any I/O cards such as network. Remove any extra memmory cards. Once the printer starts and runs without the error, plug the cards and modules back in one at a time to see which card or module returns the error. Remember to cycle power each time you replace a card or module.
I hope this helps.

Everyone of those I've ever seen on that model has been attributable to a bad DC controller board.
