Abstract: A printer includes a print portion, a connection portion, a storage device, a processor and a memory. The connection portion is configured to be USB-connected with an external device. The storage device has a mass storage area accessible by the external device connected via the connection portion. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform steps of establishing a connection with the external device via the connection portion, using a mass storage class and storing image data in the mass storage area. The image data is data representing an image. The image data is transmitted from the external device via the connection portion. The computer-readable instructions further cause the printer to perform a step of printing the image on the recording medium by controlling the print portion based on the stored image data.

Abstract: The disclosure discloses a printer including a first memory that stores computer-executable instructions that cause the printer to perform a terminal searching process, a job receiving process, and a coordination control process. In the terminal searching process, it is searched whether any of the operation terminals retains the printing job conforming to an accepting condition or not, by performing the mutually-recognized communication triggered by reception of a signal of an action-starting operation in a starting operation accepting process. In the job receiving process, in the case that some of the operation terminals retain the printing job conforming to the accepting condition, the printing job from the operation terminal is received. In the coordination control process, the printing head and the feeder are controlled in coordination with each other in the manner that the printed matter in accordance with print data in the printing job is produced.
