Final answer:
A network printer is most likely to be connected to a switch, which facilitates communication within a local network.
Step-by-step explanation:
Besides a SOHO (Small Office/Home Office) router, a network printer is most likely to be connected to a switch. This is because switches, which are networking devices, are used to connect various devices within a network by using packet switching to receive, process, and forward data to the destination device. A router can be used to connect multiple networks and direct network traffic, but within a single network, a switch is typically used to connect PCs, printers, and other devices.
