A control device suppresses modifying a program related to printer control when a connected printer is replaced with a printer having a different structure. A host computer has a print controller that can execute processes based on status data; a virtual second printing device that outputs response data when a control command output from the print controller is input; and a data processing unit that converts the input control command to a control command compatible with an inkjet printer and outputs to the inkjet printer when a control command output from the print controller is input, and when status data from the inkjet printer is input, converts the status data to data compatible with a thermal printer based on the structural differences between the inkjet printer and the thermal printer, and outputs to the print controller. |
