Printer

A printer comprising:

• a feeder configured to feed a print-receiving medium,
• a printing head configured to perform a print on said print-receiving medium fed by said feeder,
• a communicating device configured to execute mutually-recognized communication with at least one operation terminal that retains a printing job for requesting production of a printed matter in an unsent state,
• a detecting device configured to detect an accepting condition of said print-receiving medium fed by said feeder, the accepting condition being related to whether print data from said operation terminal is acceptable or not,
• a processor, and
• a first memory,
• said first memory storing computer-executable instructions that, when executed by said processor, cause said printer to perform:
• a starting operation accepting process for receiving a signal of a predetermined action-starting operation;
• a terminal searching process for searching whether any of said operation terminals retains said printing job conforming to said accepting condition detected by said detecting device or not, by means of performing said mutually-recognized communication via said communicating device triggered by reception of said signal of said action-starting operation in said starting operation accepting process;
• a job receiving process for, in the case that some of said operation terminals retain said printing job conforming to said accepting condition in said terminal searching process, receiving the printing job from the operation terminal by said mutually-recognized communication via said communicating device;
• and
• a coordination control process for controlling said printing head and said feeder in coordination with each other in the manner that said printed matter in accordance with print data included in said printing job received in said job receiving process is produced.
