Image forming device and non-transitory computer-readable recording medium storing computer-readable instructions for image forming device

A non-transitory computer-readable recording medium storing computer-readable instructions for an image forming device:

• the computer-readable instructions, when executed by a processor of the image forming device, cause the image forming device to:
• repeatedly send an inquiry request to a server, wherein in a case where the server receives a job execution instruction from a terminal device, the server sends a job execution response to the image forming device in response to the inquiry request received from the image forming device, and the job execution response indicates that a job is to be executed;
• in a case where the job execution response is received from the server, control the image forming engine to start image formation;
• and
• in the case where the job execution response is received from the server, establish a connection of server-push type with the server, wherein in a case where the server receives a job stop instruction from the terminal device, the server sends an image formation stop command to the image forming device without receiving the inquiry request from the image forming device,
• wherein in a case where the image formation stop command is received, the image formation is stopped.
