A roll sheet type stored in an apparatus/medium type table, the roll sheet wound on a roll sheet holder of each of label creating apparatuses, and a medium type selected by the user are compared to each other. If both values are equal, one of the label creating apparatuses which accommodates the roll sheet holder holding the roll sheet of the medium type is set to be the label creating apparatus to which a PC sends a print request. As a result, the label creating apparatus can be automatically selected by the PC on the basis of label data created by the PC.
