• said steps comprising:
• a detection step for detecting a type of said storage body attached to said attaching part;
• a determination step for determining on the basis of a detection result in the detection step whether the type of said storage body attached to said attaching part is a first type in an ordering state associated with insufficiency in quantity or a second type other than said first type;
• and
• a mode switching step for, in the case that the type is determined as said first type at said determination step, switching said control mode for controlling said feeder and said printing head from a normal mode prepared in advance correspondingly to said second type to a medium-saving mode prepared in advance correspondingly to said first type for reducing a consumption amount of said print-receiving medium than said normal mode.
