To warn a user of illegal power off operation when the operation is done.

A printing control method includes: an acquisition step (S301) for requesting and acquiring status information of a printer before transferring printing data to the printer; display steps (S302, S303) for displaying a warning picture when the status information acquired by the acquisition step indicates that preceding power off operation is illegal; first transmission steps (S304, S305) which, when a user responds to the warning picture, transmit a command for initializing the preceding power off state stored in the printer to the printer; and a second transmission step (S306) for transferring the printing data to the printer after transmitting the command in the first transmission steps.
