According to one embodiment, there is provided a printer including a print head, a platen roller, a sheet position sensor, an antenna, and a movable portion. The print head is configured to print on a strip-shaped sheet. The platen roller is configured to move the sheet pinched between the platen roller and the print head along a longitudinal direction of the sheet. The sheet position sensor is provided on a substrate disposed on an upstream side of the print head in a conveyance direction of the sheet, and is configured to detect a position of the sheet. The antenna is provided on the substrate and is configured to write information to a wireless tag provided on the sheet. The movable portion is configured to move the substrate along a width direction of the sheet.

An image inspection apparatus is capable of inspecting an image on a print sheet as an inspection object with high accuracy while conveying the print sheet from an upstream conveyance unit to a downstream conveyance unit. The image inspection apparatus inspects the print sheet conveyed at a first conveyance speed with a first conveyance unit of a printing device, with a first inspection unit, while conveying the print sheet at a second conveyance speed with a second conveyance unit of an inspection device. The first inspection unit is provided in a position downstream of an intermediate position between the first conveyance unit and the second conveyance unit by a length longer than a half of the length of the print sheet. Even when the first conveyance speed and the second conveyance speed are not substantially the same, no disorder occurs in the image read with the first inspection unit.

A shift amount detecting chart is formed on web paper, and the shift amount detecting chart is photographed by an image pickup unit. An image processor calculates shift amounts smaller than a maximum shift amount in absolute values as correction values based on a variation trace of density peak positions from image data corresponding to the shift amount detecting chart photographed by the image pickup unit. A controller corrects printing timing with these correction values. Consequently, even when temporal variations occur to the shift amounts within a predetermined length, since the correction values are calculated based on the shift amounts smaller than the maximum shift amount in absolute values, an excessive correction can be prevented, thereby to improve printing quality.

A printer includes head that performs printing by ejecting ink at a position of ejection of the ink in a print coordinate system, camera that captures an image of an area where the ink is ejected and outputs the image in an image coordinate system, camera capturing an image of calibration pattern printed by ejecting the ink at a calibration ejection position and outputting the image including calibration pattern, the calibration ejection position being a position at which calibration pattern is printed by ejecting the ink, and calculator that calculates the amount of displacement between the position of calibration pattern in the image coordinate system and the calibration ejection position in the print coordinate system.

A printing device includes a head and a carriage. The head has a nozzle. The head is configured to eject liquid from the nozzle toward a printing medium. The carriage is configured to move the head in a first direction. The carriage includes a first distance sensor. The first distance sensor is configured to measure a distance between the head and the printing medium. The first distance sensor is a specular reflection type distance sensor. The first distance sensor includes a light-emitting element and a light-receiving element. The light-emitting element and the light-receiving element are aligned in the first direction.

A print processing portion causes a print device to execute printing of a print image based on print data in accordance with a first scanning amount detected when manual scanning is performed at a first time. A density complementation processing portion causes the print processing portion to execute reprinting in accordance with a second scanning amount detected when the manual scanning is performed at at least a second time. When the manual scanning is performed at at least the second time, the density complementation processing portion identifies density insufficient parts in the print image printed by the print device based on the scanning amount and an image read by an optical reading device. Furthermore, the density complementation processing portion causes the print processing portion to execute the reprinting for the density insufficient parts.

the ejection amount per ejection from the nozzle when the distance between the nozzle and the recording medium is the first distance is equal to the ejection amount per ejection from the nozzle when the distance between the nozzle and the recording medium is the second distance.

Provided is a printing apparatus. The printing apparatus includes: a stage on which an object is positioned; a printing unit provided above the stage and performing printing on the object; and a control part configured to perform a correction for printing on at least one of the object, the stage, and the printing unit based on preset printing conditions, in which the printing unit includes a head frame provided above the stage, a detection sensor configured to detect a distance between the head frame and a part positioned thereunder, and a heat part provided on the head frame to perform printing on the object.

A print device prints prescribed information on a plurality of print media including at least one first medium and at least one second medium arranged subsequent to the at least one first medium on a long medium. The plurality of print media corresponds to a zone number that is smaller than a total number of the print media to be printed. The print device judges, for each of the at least one first medium, a print quality or a degree of the print quality. The judging the print quality or the degree of the print quality is based on a prescribed result obtained the print content of the at least one first medium on which the printing has been performed. The print device prints, on the at least one second medium, judgment result information indicating a result of the judging the print quality or the degree of the print quality.

A recording apparatus includes a recording unit, a conveyance unit, an application amount information acquisition unit, a determination unit, a direction information acquisition unit, and a setting unit. The recording unit performs recording by applying ink to paper. The application amount information acquisition unit acquires information related to an amount of ink that the recording unit applies to a predetermined region of the paper. The determination unit determines execution of prevention or reduction processing for preventing or reducing curling occurring after recording is performed. The determination is made according to the acquired amount of ink. The direction information acquisition unit acquires information indicating a paper grain direction of the paper relative to a conveyance direction in which the conveyance unit conveys the paper. The setting unit sets the predetermined region according to the paper grain direction relative to the conveyance direction indicated by the acquired paper grain direction information.
