PRINTING DEVICE AND COMMUNICATION PROCESSING PROGRAM

To transmit a notification of completion of execution to an external mediating device, before power supply OFF operation is executed so that transmission becomes impossible.SOLUTION: A printer 14 comprises a printing engine 51 and a CPU 41. In a second program 34, a processing execution instruction to execute predetermined processing is received from an external mediating device 12 (step S39); it is determined whether the received processing execution instruction is a first instruction under which power supply OFF operation is performed or not (steps S42, S44 and S52); a notification of completion of execution is transmitted to the external mediating device 12 when the execution of processing instructed under the first instruction is completed, when it is determined that the instruction is the first instruction (step S62); and the notification of completion of execution is transmitted to the external mediating device 12 at predetermined timing prior to completion of the execution of processing instructed under the first instruction, when it is not determined that the instruction is the first instruction (steps S46, S54 and S68).SELECTED DRAWING: Figure 4 【課題】電源ＯＦＦ動作が実行されて送信が不可能となるより前に、外部仲介装置へ実行完了報告を送信する。【解決手段】プリンタ１４は、印刷エンジン５１と、ＣＰＵ４１と、を有し、第２プログラム３４は、外部仲介装置１２から所定の処理を実行する処理実行指示を受信し（ステップＳ３９）、受信した処理実行指示が、電源ＯＦＦ動作を伴わない第１指示であるか否かを判定し（ステップＳ４２，Ｓ４４，Ｓ５２）、第１指示であると判定された場合には第１指示により指示された処理の実行完了時に実行完了報告を外部仲介装置１２に送信するとともに（ステップＳ６２）、第１指示であると判定されない場合には当該第１指示により指示された処理の実行完了より前の所定タイミングで実行完了報告を外部仲介装置１２に送信する（ステップＳ４６，Ｓ５４，Ｓ６８）。【選択図】図４
