Abstract: A piezoelectric print head includes a first discharge section, a second discharge section, a third discharge section, a first switch, a second, and a third switch. The second discharge section is located between the first discharge section and the third discharge section, the first switch and the third switch are switched in accordance with a print signal in synchronization with a first clock, the second switch is switched in accordance with a print signal in synchronization with a second clock, in a first period, the print signal synchronized with the second clock is transferred and the print signal synchronized with the first clock is not transferred, and in a second period, the print signal synchronized with the second clock is not transferred and the print signal synchronized with the first clock is transferred.
Abstract: A printing apparatus, including: a head holder; a platen roller; a first support shaft; a roller holder; a moving mechanism configured to move the roller holder; and a biasing member configured to bias the roller holder in an inclined direction inclined with respect to a first direction which is substantially orthogonal to a conveyance direction and in which the roller faces a thermal head toward a second direction side, the second direction opposite to the conveyance direction, wherein, in a state in which the roller holder is located at a pressing position, the roller is held in contact with the head while receiving a biasing force in the first direction from the biasing member, and a first contact portion of the roller holder is held in contact with the head holder in the second direction while receiving a biasing force in the second direction from the biasing member.
Abstract: An inkjet recording apparatus includes: a tank having ink chamber; a recording head; a memory storing a count value updated toward a first threshold value in accordance with ejection of ink; a display; an operation interface; a power switching section switched between a first state and a second state; and a controller executes a first inquiry process to: display a first inquiry screen inquiring whether the ink chamber has been refilled with ink; and receive one of a first operation and a second operation.
