Non-transitory computer readable medium recorded with program and liquid ejecting apparatus

A non-transitory computer readable medium recorded with a program for controlling an external apparatus configured to communicate with a liquid ejecting apparatus including a head having a plurality of nozzles and a memory configured to store nozzle-information relevant to a state of abnormality of a nozzle in the plurality of nozzles, wherein

• the program allows the external apparatus to execute:
• acquiring first information corresponding to the nozzle-information from the liquid ejecting apparatus;
• judging whether or not second information is to be acquired from the liquid ejecting apparatus based on the first information, the second information being information corresponding to the nozzle-information and the second information having a data amount larger than that of the first information;
• and
• in a case that it is judged that the second information is to be acquired from the liquid ejecting apparatus, acquiring the second information from the liquid ejecting apparatus, wherein
• the first information is information relevant to the number of abnormal nozzles each having abnormality to eject the liquid, of the plurality of nozzles of the head, and
• in a case that it is judged whether or not the second information is to be acquired, and in a case that the first information indicates that the number of the abnormal nozzles is not less than a threshold value, then it is judged that the second information is to be acquired from the liquid ejecting apparatus.

• in a case that it is judged that the second information is to be acquired from the liquid ejecting apparatus, acquiring the second information from the liquid ejecting apparatus, wherein
• the liquid ejecting apparatus includes a recovery unit configured to perform a recovery action in order to recover any abnormal nozzle having abnormality to eject the liquid by discharging the liquid from the nozzle,
• the first information is information relevant to the number of abnormal nozzles of the plurality of nozzles of the head and the number of unrecoverable nozzles incapable of being recovered as the abnormal nozzles which cannot be recovered by the recovery action, and
• in a case that it is judged whether or not the second information is to be acquired, and in a case that the first information indicates that a number, which is obtained by subtracting the number of the unrecoverable nozzles incapable of being recovered from the number of the abnormal nozzles, is not less than a threshold value, then it is judged that the second information is to be acquired from the liquid ejecting apparatus.

A non-transitory computer readable medium recorded with a program for controlling an external apparatus configured to communicate with a liquid ejecting apparatus including a head having a nozzle and a memory configured to store nozzle-information to indicate a state of the nozzle, wherein the program allows the external apparatus to execute:

• acquiring first information corresponding to the nozzle-information from the liquid ejecting apparatus;
• judging whether or not second information is to be acquired from the liquid ejecting apparatus based on the first information, the second information being information corresponding to the nozzle-information and the second information having a data amount larger than that of the first information;
• and
• in a case that it is judged that the second information is to be acquired from the liquid ejecting apparatus, acquiring the second information from the liquid ejecting apparatus, wherein
• the first information is information relevant to whether or not the nozzle-information, which is stored in the memory of the liquid ejecting apparatus, is updated from the nozzle-information which was stored in a case that the liquid ejecting apparatus transmitted the second information last time, and
• in a case that it is judged whether or not the second information is to be acquired, and in a case that the first information indicates that the nozzle-information is updated, then it is judged that the second information is to be acquired from the liquid ejecting apparatus.

• the first information resides in individual pieces of information in relation to the plurality of first nozzles and the plurality of second nozzles,
• in a case that it is judged whether or not the second information is to be acquired, it is individually judged whether or not the second information relevant to the plurality of first nozzles is to be acquired from the liquid ejecting apparatus and whether or not the second information relevant to the plurality of second nozzles is to be acquired from the liquid ejecting apparatus, and
• in a case that the second information is acquired, only the second information, which is judged to be acquired in the judging process and which is included in the second information relevant to the plurality of first nozzles and the second information relevant to the plurality of second nozzles, is acquired from the liquid ejecting apparatus.
