A printing device printing on a medium while being manually moved in relation to the medium is provided. The printing device includes: a speed detection unit detecting a speed of movement at which the printing device is moved; and a stop control unit stopping the printing when the speed of movement exceeds a threshold.

An inkjet printer capable of improving uniformity of the quality of an image printed on a recording medium is provided and includes: a table formed with a support surface that supports a recording medium; an inkjet head formed with a nozzle that ejects ink; a Y-bar that supports the inkjet head to be movable in a main scanning direction; two lifting mechanisms capable of changing a Y-bar tilt serving as a tilt of the Y-bar with respect to the support surface; a head gap sensor that detects a head gap, which is a distance from the recording medium to the nozzle of the inkjet head; and a tilt adjustment portion that adjusts the Y-bar tilt by the two lifting mechanisms to a tilt that reduces variations of the head gaps detected by the head gap sensor at each of multiple positions in the main scanning direction.

A liquid ejecting device includes a head configured to eject liquid, a holding unit holding the head, a base unit holding the holding unit, a guide unit movably holding the base unit, the guide unit being configured to guide the base unit, and a detection unit attached to the base unit, the detection unit being configured to detect vibration of the base unit, in which the base unit includes a first surface and a second surface opposite to the first surface, the guide unit is attached to the first surface, and the detection unit is attached to at least one of the first surface and the second surface.

A printer for direct printing on a print substrate comprises a front support supporting a printing device; the front support to be arranged at a front side of a print substrate and to be aligned relative to a rear support across the print substrate in a contact-less manner.

A liquid discharging apparatus, having a head with nozzles, a scanning assembly, a conveyer, and a controller, is provided. The controller is configured to determine whether the nozzles are to be flushed in a moving action which accompanies a discharging action, if the controller determines the nozzles are not to be flushed in the moving action, conduct the moving action to move the head at a first acceleration rate; if the controller determines the nozzles are to be flushed in the moving action, determine whether a distance between a flushing range and a discharging range is greater than or equal to a predetermined distance; and if the controller determines the distance is greater than or equal to the predetermined distance, conduct the moving action to move the head at a second acceleration rate and control the head to discharge liquid for flushing the nozzles.

In example implementations, a method, a device, and a program are provided. The method includes detecting a power increase movement of a printer carriage. A location of the printer carriage is detected at a time of the detected power increase. Based on the detected location of the printer carriage, determine whether the print medium is damaged. The device includes a power monitor to detect a power increase during movement of a printer carriage. A locator detects a location of the printer carriage at the time of the detected power increase. A damage determiner determines, based on the detected location of the printer carriage, whether the print medium is damaged. The program detects a power increase during movement of a printer carriage. Location of printer carriage is detected at time of detected power increase. Based on detected location of the printer carriage, it is determined whether the print medium is damaged.

A printer is provided with a first nozzle surface including a first nozzle row, a second nozzle surface including a second nozzle row positioned with respect to the first nozzle row in a main scanning direction, a receiver having a width smaller than an interval between the first nozzle row and the second nozzle row, and a driver. A processor of the printer causes the driver to perform a discharge driving to discharge ink from at least one of nozzles of one of the first nozzle row or the second nozzle row, and causes the driver to perform a non-discharge driving to not discharge ink from at least one of nozzles of the other of the first nozzle row or the second nozzle row, in a state of one of the first nozzle row or the second nozzle row being caused to face the receiver in a discharge direction.

A printing apparatus includes a carriage mounted with a printing unit configured to perform printing on a print medium, a first motor used to move the carriage, a second motor used together with the first motor to move the carriage, and a control unit configured to control the first motor and the second motor. When moving the carriage, the control unit controls the first motor with a first control amount and controls the second motor with a second control amount. The first control amount and the second control amount are different from each other, and a ratio therebetween is a predetermined ratio.

A printing apparatus includes: a carriage mounted with a printing unit; a first motor configured to move the carriage in a predetermined direction; a second motor configure to move the carriage in the predetermined direction; and a control unit. The control unit executes a first mode in which, when causing the printing unit to perform printing under a first printing condition, the first motor is driven in a first direction and the second motor is driven in a second direction, and a second mode in which, when causing the printing unit to perform printing under a second printing condition different from the first printing condition, the first motor is driven in the first direction and the second motor is driven in the second direction while changing an output ratio between the first motor and the second motor.

The printing apparatus includes a carriage having a print head mounted thereon, a carriage guide configured to guide movement of the carriage and to support the carriage, an optical scale member having an optical scale, an optical sensor mounting member having an optical sensor mounted thereon to read the optical scale, the optical sensor mounting member being fixed to a support surface of a support wall of the carriage, and a head portion of the fixing screw configured to be switched between a fixed state in which the optical sensor mounting member is fixed to the carriage and a release state in which the fixed state is released. The head of the fixing screw is located on a side opposite to the support surface with respect to the support wall when the optical sensor mounting member is in the fixed state.
