A liquid discharge apparatus includes multiple liquid discharge heads, a medium mover, and circuitry. The multiple liquid discharge heads include a first liquid discharge head to discharge a treatment liquid onto a region of the medium and a second liquid discharge head to discharge a color liquid onto the region to paint the region, on which the treatment liquid is applied, in a predetermined color. The circuitry causes the first and second liquid discharge heads to form an evaluation chart. The evaluation chart includes patterns different in a combination of a first discharge amount of the treatment liquid and a second discharge amount of the color liquid. Further, the circuitry performs a setting of the first discharge amount with respect to the second discharge amount according to the coloring, and causes the second liquid discharge head to discharge the treatment liquid onto the region based on the setting.

A tape printing apparatus includes an operation surface and a plurality of operation keys protruding from the operation surface. The operation keys include first keys and second keys that protrude less than the first keys from the operation surface, and the second keys include at least one of a power key and a print key.

A liquid ejecting head includes a pressure generating unit in order to eject liquid from a nozzle that is provided on a nozzle surface, a case in order to accommodate the pressure generating unit, and a guide portion that is provided on a side surface of the case, in which in a case of being viewed from a first direction orthogonal to the nozzle surface, the guide portion has projecting portions facing one end side in a second direction along the nozzle surface, and recessed portions facing the other end side in the second direction.

A portable large format inkjet printer for printing an image at a media print area of a stationary flat media includes an inkjet print engine having a printhead carrier system configured to dynamically scan an inkjet printhead over the media print area in each of two orthogonal directions during the printing of the image. An alignment frame is configured to fixedly mount the inkjet print engine to facilitate a manual positioning of the alignment frame and the inkjet print engine in unison. The alignment frame has an open interior window within which the inkjet printhead is moved and from which all printing occurs. At least one alignment panel is mounted to the alignment frame. Each respective alignment panel has an alignment indicia configured to facilitate accurate manual positioning of the portable large format inkjet printer at a desired printing position at the media print area.

A liquid ejecting unit includes: a print head having a first electrically coupling portion and configured to eject ink; an electric member having a second electrically coupling portion configured to couple the first electrically coupling portion; a support portion for supporting the print head; a shaft protruding from the support portion in a protruding direction; and a fixing member, the print head has a head through hole, the electric member has a first through hole, and the print head and the electric member are fixed to the support portion by engagement between the shaft and the fixing member in a state in which the shaft is inserted into the head through hole and the first through hole in this order.
