Today the office printer produced three sheets with what seems to be random characters, and in the middle a string random1random2random3random4. This raised a red flag with us. Is this something to be worried about? We use the full stack of Meraki Go (router, switch, AP) with Cisco Umbrella subscription activated for the router. The printer model is Brother DCP-L5500DN, which is connected over ethernet directly to the router. Here are the prints: Could this be an attack? Any advice on how to approach this from here on? Thanks!
