To keep it short, it is neither, the motherboard is the centre, the hub, and all the input and output devices must be connected to it. The other devices only become input / output devices because the motherboard (which contains the CPU) either reads data from them or sends data to them.
A computer keyboard is an INPUT device not an OUTPUT device.
input to any system by means of key board,mouse,scanner etc known has input device. The processed output is taken by means of spekers,printer,monitor known as output device.

A printer is an output device. The keyboard is an input device.
A motherboard is nor an output nor an input device. It is in the middle of these two and is a processing hardware device
