A label production processing program that when executed on arithmetic means of an operation terminal comprising display means and said arithmetic means, to operate a label producing apparatus configured to print on a print-receiving medium configured to be attached to and detached from an apparatus housing and configured to produce a label, causes said arithmetic means to perform: an identification information acquisition step for acquiring identification information of said label producing apparatus from at least one of a plurality of label producing apparatuses configured to be information-transmittably and information-receivably, characterized by a medium information acquisition step for acquiring medium information on said attached print-receiving medium from said label producing apparatus from which said identification information has been acquired, wherein said medium information acquisition step acquires as said medium information attachment and detachment type information that indicates whether a print-receiving tape as said print-receiving medium is attached to and detached from said apparatus housing as a tape roll wound in a rolled form, or said print-receiving tape is attached to and detached from said apparatus housing as a cartridge which stored said tape roll in a case; and a display step for displaying on said display means menu screens (106A, 106B) in which said identification information and said medium information corresponding to said identification information are displayed as a list, to set alternatively said label producing apparatus which is a print output destination from among said at least one of the plurality of label producing apparatuses, said arithmetic means is further caused to execute: a maximum size information acquisition step for acquiring maximum size information of said print-receiving medium configured to being dealt with by said label producing apparatus from which said identification information has been acquired; wherein: said display step, in a case where said print-receiving medium has not been attached to said apparatus housing, displays on said display means said menu screen in which said identification information and said maximum size information corresponding to said identification information are displayed as a list, and said display step, in a case where said print-receiving medium has been attached to said apparatus housing, displays on said display means said menu screen in which said identification information, and said medium information and said maximum size information corresponding to said identification information are displayed as a list. an identification information acquisition step for acquiring identification information of said label producing apparatus from at least one of a plurality of label producing apparatuses configured to be information-transmittably and information-receivably, characterized by a medium information acquisition step for acquiring medium information on said attached print-receiving medium from said label producing apparatus from which said identification information has been acquired, wherein said medium information acquisition step acquires as said medium information attachment and detachment type information that indicates whether a print-receiving tape as said print-receiving medium is attached to and detached from said apparatus housing as a tape roll wound in a rolled form, or said print-receiving tape is attached to and detached from said apparatus housing as a cartridge which stored said tape roll in a case; and a display step for displaying on said display means menu screens (106A, 106B) in which said identification information and said medium information corresponding to said identification information are displayed as a list, to set alternatively said label producing apparatus which is a print output destination from among said at least one of the plurality of label producing apparatuses, said arithmetic means is further caused to execute: a maximum size information acquisition step for acquiring maximum size information of said print-receiving medium configured to being dealt with by said label producing apparatus from which said identification information has been acquired; wherein: said display step, in a case where said print-receiving medium has not been attached to said apparatus housing, displays on said display means said menu screen in which said identification information and said maximum size information corresponding to said identification information are displayed as a list, and said display step, in a case where said print-receiving medium has been attached to said apparatus housing, displays on said display means said menu screen in which said identification information, and said medium information and said maximum size information corresponding to said identification information are displayed as a list. said display step, in a case where said print-receiving medium has not been attached to said apparatus housing, displays on said display means said menu screen in which said identification information and said maximum size information corresponding to said identification information are displayed as a list, and said display step, in a case where said print-receiving medium has been attached to said apparatus housing, displays on said display means said menu screen in which said identification information, and said medium information and said maximum size information corresponding to said identification information are displayed as a list.
