Communicate to non-Technical people
Q: "Why did my computer do that?"
Tell them their computer saw how hard they were working and wanted to give them a break. If it has to do with printers, tell them it's because printers are the Ice Cream Machine of the IT World they are always broken and nobody knows why. You can also follow up with a brief explanation. Eg:
“I think something in the software that talks to the printer got a little wonky and restarting made it start up fresh.”
