特徴とするプリンタの信号処理装置。[Claims for Utility Model Registration] A changeover switch circuit in which a plurality of component signals constituting a video signal to be supplied to a printer are supplied to each of a plurality of input terminals, and which sequentially switches the component signals and outputs them as signals in sequence; A changeover switch is provided that switches between a first changeover control signal that is supplied to the switch circuit and controls the changeover at a predetermined timing, and a second changeover control signal that is supplied to the changeover switch circuit and controls the changeover at an arbitrary timing. A signal processing device for a printer, characterized in that the changeover switch is configured to arbitrarily switch between the first changeover control signal and the second changeover control signal and supply the signals to the changeover switch circuit.
