Which 2 interface types can supply power to a scanner or a printer?

Two interface types that can supply power to a scanner or printer are USB (Universal Serial Bus) and Power over Ethernet (PoE). USB interfaces, particularly USB-C, can deliver power alongside data transfer, making them common for many peripherals. Power over Ethernet allows devices to receive power through an Ethernet cable, which is useful for networked printers and scanners in office environments.
