摘要： A peripheral device for a computer is disclosed, which employs desired code setting means for determining a desired code and a comparator for comparing the thus determined code and a command from a host computer, whereby the control operation can be smoothly effected by the command from the host computer. Also, a graphic printer is provided as a peripheral device which employs a plurality of sampling clocks of which the phases are different from that of a reference sampling clock. These sampling clocks are selectively used to enable a video signal of a different phase from a computer to be printed out excellently.
