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.

Liquid ejecting apparatus and moving unit including detector that detects change in posture of carriage

A liquid ejecting apparatus includes: a support that extends in a second direction intersecting a first direction in which a printing medium is transported; a carriage that is connected to the support and is movable in the second direction; an ejector that is provided in the carriage and ejects a liquid to the printing medium; and a detector that is provided in the carriage and detects a change in posture of the carriage. In a case where the liquid is not ejected from the ejector, the carriage moves in the second direction, and the detector detects the change in posture of the carriage. The detector outputs posture-change amount information based on the change in posture of the carriage. Ejection of the liquid is corrected based on the posture-change amount information.

INKJET PRINTING APPARATUS AND INKJET PRINTING METHOD

Images with high image quality having less time-difference unevenness are outputted in an inkjet printing apparatus that performs multi-pass printing using full-line inkjet print heads 2. For this purpose, a CPU is capable of setting a first printing method in which an image for a unit area is printed by a specified number of printing conveyance operations and a second printing method in which an image for a unit area is printed by a smaller number than the specified number of printing conveyance operations. The CPU sets conveyance conditions such that a taken time for one printing conveyance operation of the printing conveyance operations for a unit area in the second printing method is smaller than a taken time for one successive printing conveyance operation of the printing conveyance operations for a unit area in the first printing method.
