In an image processing device, a controller is configured to perform: selecting; generating; and outputting. The selecting selects a target partial image one by one from a plurality of partial images. The target partial image is represented by target partial image data. The generating generates partial print data for a partial print by executing an image process on the target partial image data. The partial print forms the target partial image while moving a print head in a printing direction. The partial print forms the target partial image while moving a print head in a printing direction. The image process includes a color conversion process. The color conversion process is executed on the target partial image data using one of a first profile and a second profile selected in accordance with the printing direction set for the partial print. The outputting outputs the partial print data to the printer.

A printer has first and second print sections 100, 200 joined along a line 12, and a controller 50. Each section contains a printhead 120; 220 travelling on a track 110; 210. A frame or frame part 104 supports the track and is driven on wheels by a motor, so that the printer can travel autonomously along a horizontally extending step edge, printing as it goes. It further includes a sensor for detecting the proximity of the vertical face 5v of the step. The printer can thus be set to print advertising, for instance, on the steps of a stadium.

A control device includes: a memory; and a controller. A printer includes: a head; and a carriage mounting the head thereon. The controller is configured to perform: selecting first speed information from among a plurality of pieces of speed information stored in the memory, the first speed information indicating a first speed; estimating an ink pressure related value using the first speed information, the ink pressure related value indicating an ink pressure for a first type of print printing an image by ejecting ink from the head while moving the carriage at the first speed; determining whether the ink pressure related value reaches a threshold value; executing the first type of print in response to determining that the ink pressure related value does not reach the threshold value; and executing a second type of print in response to determining that the ink pressure related value reaches the threshold value.

An electric apparatus for controlling movement of a target object by performing first and second feedback controls, based on a detection signal obtained from detecting the movement of the target object, generates an operation quantity on the target object based on first and second operation quantities for the second feedback control if one of a predetermined target value and an estimated first state quantity of the target object is higher than a first threshold value, and generates the operation quantity on the target object using only the first operation quantity from among the first and the second operation quantities if one of the target value and the first state quantity of the target object is lower than the first threshold value.

An ink-jet printing apparatus includes: a conveying part that conveys a print medium; a plurality of discharge heads that is arranged along a direction of conveying the print medium, and discharges ink onto the print medium to perform printing an the print medium; a moving part that moves the discharge heads such that distances between the print medium and the discharge heads are changed from a set distance; and a hardware processor that controls printing on the print medium, wherein the hardware processor corrects a print distance such that the print distance is changed from a predetermined value in response to the discharge heads being moved in such a way as to change the distances between the print medium and the discharge heads, the print distance being a conveying distance of the print medium to be conveyed While printing on the print medium is performed by the discharge heads.

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 printing apparatus includes: a head portion that discharges droplets toward a printing medium while reciprocating on the printing medium; and a controller that controls movement of the head portion during a printing operation such that a movement stop time of the head portion when a movement direction of the head portion is reversed at an endmost portion of a range in which the head portion moves is longer than the movement stop time of the head portion when the movement direction of the head portion is reversed on the printing medium.

A printing apparatus includes: a platen that supports a printing medium; a head-portion that discharges droplets toward the printing medium while reciprocating on the printing medium; an interval-adjusting-mechanism that adjusts an interval between the platen and the head-portion; and a controller that controls the head-portion and the interval-adjusting-mechanism, in which the controller has a first printing mode in which printing is performed while the interval is set to a first interval and a second printing mode in which the printing is performed while the interval is set to a second interval that is larger than the first interval, as a printing mode in which the printing is performed on the printing medium. The controller controls movement of the head-portion such that a movement stop time of the head-portion when a movement direction of the head-portion is reversed is longer in the second printing mode than in the first printing mode.

There is provided a liquid discharge apparatus including: a liquid discharge head having a nozzle surface; a carriage; a carriage mover; a conveyor conveying a medium in a conveyance direction; a velocity sensor; a distance sensor; and a controller. The controller makes a determination regarding the velocity of the carriage based on output of the velocity sensor, and makes a determination regarding the distance between the medium and the nozzle surface based on output of the distance sensor. In a case that that the controller determines that the velocity is less than a predetermined velocity and that the distance is less than a predetermined distance, the controller interrupts recording performed by the liquid discharge head.

There is provided an image recording apparatus including a carriage, a head, a velocity sensor, and a controller. The controller obtains velocity data of the carriage from the velocity sensor, determines a threshold value based on the velocity data, records an image on a recording medium, and suspends a recording pass when the controller has determined that a velocity indicated by the velocity data is lower than a velocity corresponding to the threshold value. The controller can execute a first recording mode and a second recording mode in which the velocity of the carriage is faster than that of the first recording mode. The velocity data for the first recording mode is obtained in a warm-up time after a recording command is received until recording of the image is started. The velocity data for the second recording mode is obtained in other time other than the warm-up time.
