Abstract: A terminal device may acquire first connection information including a plurality of parameters, and send the first connection information to a communication device by using a first wireless connection and not via an access point. The first connection information is used in the communication device to execute a process for establishing a wireless connection with a target access point. The terminal device may receive a failure notification indicating that the process has failed from the communication device by using the first wireless connection and not via an access point in a case where the process in the communication device has failed, and display a cause screen indicating that the process has failed due to the specific parameter on a display unit in a case where the failure notification is received from the communication device.

Abstract: A printing apparatus includes: a conveyor configured to convey a printing medium; a printing device configured to perform printing on the printing medium conveyed by the conveyor; a connector configured to accept a connecting cable connectable to a code reader; a storage configured to store setting information indicating a setting of the code reader; and a controller configured to control the conveyor and the printing device. The controller being configured to execute a setting-code-printed-material creating processing in which the controller controls the conveyor and the printing device to create a setting-code printed material by printing a setting code corresponding to the setting information stored in the storage, on the printing medium.

Abstract: The disclosure discloses a portable printer including a feeder, a printing head, a controller, and a command transmission unit. The feeder is configured to feed a print-receiving medium. The printing head is configured to perform print on the print-receiving medium fed by the feeder. The controller is configured to control the feeder and the printing head in cooperation with each other to produce a first printed matter by using desired first print data. The command transmission unit is configured to transmit through wireless communication to another printer other than the portable printer a production instruction for a second printed matter having print contents equivalent to the first printed matter at a predetermined timing after start of production of the first printed matter.
