A printing device includes a housing, a print head, a scanner, and a processor. The print head includes print elements arranged linearly in a set direction in the housing. The scanner is disposed ahead of the print head in a scan direction that intersects the set direction and is a direction in which the housing is moved and acquires an image of a print medium. When determining that the image acquired by the scanner includes a reference pattern that serves as a reference of an intended position at which a print subject is to be printed, The processor controls the print head to print the print subject at the intended position that is a set distance away from a position of the reference pattern in the scan direction and is adjusted in the set direction based on the position of the reference pattern.

Examples described herein relate to printhead alignment in a printing system which may print onto media of different rigidity. An example method comprises determining a flatness profile for a first type of print medium on a platen of a printing apparatus. Using the flatness profile of the first type of print medium, first alignment compensation values are determined for a printhead to print onto the first type of print medium on the platen. The flatness profile for the first type of print medium is then also used to determine second alignment compensation values for the printhead to print onto a second type of print medium on the platen, the second type of print medium being more rigid that the first type of print medium.

Perform printing by a printing portion onto the printing paper sheet after collating a content of a code optically or electromagnetically read by a reading device connected to a printer main body and a content of printing data supplied from a memory connected to this printer main body.

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.

A printing apparatus includes a transport unit that transports a medium in a transport direction, a support portion that supports the medium that is transported by the transport unit in a width direction that intersects with the transport direction, a printing unit that performs printing on a front surface of the medium which is supported by the support portion, a detecting unit that receives reflected light which is emitted on a rear surface of the medium that is transported on a detection position that is provided in a transport path of the medium, and a light-shielding portion that faces the detecting unit with the medium interposed therebetween during at least transport of the medium by the transport unit.

An image forming device includes an input unit to which image data are input, an image processing unit that performs image processing and generates output data, and an output unit that executes a job on the basis of the output data. The image processing unit, in a vertical width compaction process, recognizes a field enclosed by borders; determines whether the recognized field is a vertical width compaction candidate field; sets a vertical omission band in such a way as to include the blank and part of the border of the vertical width compaction candidate field, without eliminating information; eliminates the vertical omission band of the image data; and shifts and compacts the image data below the vertical omission band in the upward direction.
