Hello,
Would it be correct to assume that the printer is connected to a Wi-Fi router via Ethernet? A connection to a router (such as an AirPort base station) via USB is not supported for AirPrint.
As you know, this is a printer supporting the driverless AirPrint technology. However, is AirPrint also enabled? Until now (including macOS Catalina 10.15), a "normal" printer driver has been available. When/if such a driver does not work with macOS 11 Big Sur, the printer will have to rely upon its AirPrint ability.
If you have access to an iPhone or iPad, you could check whether the M2825ND appears there as an AirPrint printer.
If not, you may have to check whether AirPrint has been enabled on the printer:

Additionally, you may want to check the router settings (Bonjour/mDNS, IPP).
