In a printing device, a controller is configured to perform: (a) writing; (b) printing; (c) determining; (d) conveying; (e) writing; (f) printing; and (g) writing. The (a) writing writes prescribed information to an information storage medium provided in a first print medium. The (b) printing prints a prescribed image on the first print medium. In response to determining in (c) that the printing quality of the prescribed image is not good for the first print medium, the (d) conveying conveys a continuous medium in a reverse direction, the (e) writing writes void information to the information storage medium provided in the first print medium, the (f) printing prints a VOID image on the first print medium after the (e) writing is performed, and the (g) writing writes the prescribed information to the information storage medium provided in a second print medium prior to performing the (f) printing.

This inkjet printing device comprises a conveyance path by which a sheet to be assembled as a corrugated cardboard box having a plurality of walls is conveyed in a conveyance direction, and inkjet heads that are positioned facing the surface of the sheet in the conveyance path and that can print a printed pattern in predetermined print ranges of an intersecting direction that intersects the conveyance direction along the surface of the sheet. The inkjet heads are positioned so that the print ranges span between first regions, which are intended to be first walls when the sheet is assembled into a corrugated cardboard box, and second regions, which are adjacent to the first regions in the intersecting direction and are intended to be second walls separate from the first walls.

A manufacturing method of a printed material that stores machine-readable information, includes forming, on a base material, a first layer including a first code symbol that is machine-readable and represents first information, using a first coloring material, and forming, on the first layer, a second layer including a second code symbol that is machine-readable and represents second information, using a second coloring material that is different from the first coloring material and decolorable at a particular temperature, such that the first code symbol is at least partly covered by the second coloring material.

There is provided a non-transitory computer-readable storage medium storing computer-readable instructions for an information processing apparatus including a processor. The computer-readable instructions, when executed by the processor, cause the information processing apparatus to perform: (a) acquiring an address of a web page currently displayed on a display of the information processing apparatus; (b) generating a code image representing the address acquired in (a); and (c) generating print data for printing the code image generated in (b).

A card processing device may include a card reader and a printer. The printer may include an ink ribbon cartridge; a thermal head; and a cover member. The ink ribbon cartridge may include a supply roll and a take-up roll. The thermal head may heat the ink ribbon and transfer ink to the card. The card reader may be on a front side of the thermal head, and a part of the card reader may be on a lower side of the supply roll or the take-up roll. The cover member may pivot between a closed position and open position. A conveyance path may be provided inside the card reader and the printer. A part of the conveyance path inside the card reader may be a first conveyance path. The card reader may include an upper frame. The upper frame may pivot between a closed position and open position.
