Disclosed is a thermal print apparatus including a medium detection sensor arranged from a thermal head at a distance shorter than an outer circumferential length of the platen roller, and a controller. The controller determines that the print medium is wrapped around the platen roller if the print medium is not detected by the medium detection sensor even when the print medium is fed by a feed amount at which the leading edge of the print medium reaches the medium detection sensor after starting of printing on the print medium. In this case, the print medium is fed backward by reversely rotating the platen roller.

A thermal printer includes a conveyance unit, a thermal head with heating elements arranged in a line crossing a conveyance direction of a thermal paper, and a controller that generates print dot data for dots to be printed by the thermal head and controls the conveyance unit and thermal head according to the print dot data. The controller determines whether the total number of dots to be printed in a predetermined number of consecutive lines of the print dot data is greater than a threshold number and, when the total number of dots is greater than the threshold number, control the conveyance unit to convey the thermal paper after the printing of the print dot data by a predetermined amount along the conveyance direction.

A media feed appliance can include a media pull guide to guide a print medium through a path while the print medium is manually pulled through the media feed appliance. The media feed appliance can also include a drive gear that is manually driven using frictional contact with the print medium while the print medium is pulled over a surface of the drive gear. The media feed appliance can also include a printer positioning port to position a manually actuatable printer to print on the print medium, wherein the drive gear of the media feed appliance is positioned to mechanically engage with a printer gear when the manually actuatable printer is docked at the port.

Some examples include a print system including a memory to store instructions and print data of a print job, a processor to execute the instructions in the memory to reference print data of a print job, determine a print parameter of the print job, and transform the print data and the print parameter into a conditioning modifier. The print system includes a print engine to dispense a print substance on a medium based on the print data to generate printed medium, and a conditioner to apply heat and pressure to the printed medium, the conditioner including a pressure roller assembly, and a controller to selectively increase a transport speed the pressure roller assembly based on the conditioning modifier and a position of the printed medium relative to the pressure roller assembly to selectively increase the speed of the printed medium through the conditioner.

A printing apparatus includes a feeding unit, a conveyance unit, a cutting unit, and a control unit. The conveyance unit nips the print medium conveyed from the feeding unit by a first roller and a second roller, and conveys the nipped print medium. The cutting unit cuts the print medium. The control unit: (1) performs control to make a command speed of the first roller lower than a command speed of the second roller until a printhead printing reaches near a trailing edge of a printing length after printing has started, (2) performs control to make the command speed of the first roller higher than the command speed of the second roller when the printing has reached near the trailing edge of the printing length, and (3) subsequently controls the cutting unit configured to cut the print medium.

There is provided a printer including: a printing part which is provided with: a conveyor configured to convey a medium in a conveying direction, a printing head having a plurality of nozzles from which an ink of a specified color is discharged and of which positions in the conveying direction are mutually different, the printing head being configured to discharge the ink from the plurality of nozzles to the medium so as to form dots in the medium, and a facing member configured to be capable of facing a print surface of the medium on an upstream side in the conveying direction with respect to the plurality of nozzles of the printing head; and a controller.

A printing apparatus provided with a transportation mechanism for a printing medium includes: a storage configured to store a machine-learned model that outputs a setting value of the transportation mechanism for causing, based on state variables including a print length as a length of a print product printed on the printing medium, the print length to be close to a reference; and a processor configured to perform printing by controlling the transportation mechanism in accordance with the setting value acquired based on the machine-learned model.

An object of the present invention is to improve throughput of continuous printing in an image printing apparatus having a cutting device that needs to be returned to a standby position for a next cutting operation. One embodiment of the present invention is an image printing apparatus having a printing unit, a conveyance unit capable of conveying a printing medium in a conveyance direction or in a returning direction opposite to the conveyance direction; and a cutting unit provided at a cutting position on a downstream side in the conveyance direction of the printing unit and configured to cut the printing medium by moving in a first direction and return to a cutting standby position for a next cutting operation by moving in a second direction opposite to the first direction.
