A printer includes a driving roller to move a medium supported on a support table in a predetermined transportation direction, and pinch roller assemblies each including a pinch roller, a support to support the pinch roller to allow the pinch roller to contact, or to be spaced from, the driving roller, and an actuator provided upstream in the transportation direction with respect to the pinch roller. The actuator includes a contact portion contactable with the support, and an operation portion to press the contact portion to the support to move the pinch roller in a direction away from the driving roller.

A liquid ejection apparatus includes a conveying unit, a winding unit, a printing unit, and a rotation control unit. The conveying unit is configured to intermittently convey a printing medium by a predetermined feed amount. The winding unit is configured to wind the printing medium conveyed by the conveying unit. The printing unit is configured to perform printing on the conveyed printing medium. The rotation control unit is configured to control the winding unit to rotate in a winding direction at a predetermined timing after the conveying unit has started to convey the printing medium intermittently, and then cause the winding unit to rotate in a reverse direction opposite to the winding direction.

An image forming apparatus is provided. The image forming apparatus includes a printing engine, a paddle device, a stapler device, and a processor. The printing engine is to form an image on a printing paper. The paddle device is to move the printing paper ejected from the printing engine in a moving direction to align a first end of the printing paper. The stapler device is to staple the align printing paper. The processor is to control the paddle device and the stapler device to move a second end of the aligned printing paper in an opposite direction to the moving direction when the first end of the printing paper is aligned.

A printing apparatus includes a printing unit configured to perform printing onto a printing medium, a driving roller configured to provide a transporting force to the printing medium, a plurality of driven rollers configured to press the printing medium, which is transported by the driving roller, and configured to rotate in conjunction with a movement of the printing medium, a plurality of support members each being configured to support a roller shaft serving as a rotation axis about which each of the plurality of driven rollers rotates, a base body to which the plurality of support members are attached, and an attachment/removal mechanism configured to cause the plurality of support members to be removably attachable individually to the base body.

The present invention relates to a movable thermal printing device, which comprises a gear set, a pressing roller set, and a heating component. The gear set includes a first motor, a first gear, and a rack gear. The pressing roller set includes a frame, a first roller, and a second motor. A sensing medium is attached below the first roller. When the first gear rotates counterclockwise, the rack gear, the pressing roller set, and the sensing medium will be driven to move upwards and away from the heating component. When the first gear rotates clockwise, the rack gear, the pressing roller set, and the sensing medium will be driven to move downwards and contact the heating component for printing sensing medium and for avoiding the sensing medium from contacting the heating component in reverse rotation and thus avoiding the problems of damages or print failure.

Printing techniques for print media are described herein. In an example, a printer includes print head and a feed roller to move a medium under the print head along a print path. The print head includes a first set of nozzles such that the first set of nozzles is proximal to the feed roller. Further, the print head is to print on a Top-of-Form (TOF) of the medium through the first set of nozzles.
