Final answer:
The best solution is to install a battery backup for the printer.
Step-by-step explanation:
The best solution to resolve the continuing issue with the printer in the Dion training offices is to install a battery backup for the printer.
When there is a power outage, the printer loses power and stops working. By installing a battery backup, the printer will continue to receive power from the backup battery, even during power outages, allowing it to keep functioning.
Replacing the printer with a new model or connecting it to a different network switch would not address the power outage issue, while switching to a wireless printer connection may introduce other connectivity or security concerns.
