Hii my name is Luna Fallon i am from the technical team if you are facing a problem then you can visit our site.There could be numerous reasons why your brother's printer is offline. It often goes offline when the printer is not securely linked to the system. Outdated drivers may possibly be the cause of the issue since they prevent the printer from interacting with the system. Check your wired connections or verify that your printer is not in power saving mode.
