A printer includes a printer main body that performs printing on a medium, a supporting frame that supports the printer main body from a lower side, a tension applying mechanism including a tension bar that comes into contact with a medium before printing and applies a tension to the medium, and a first roll attaching portion and a second roll attaching portion to which the medium before printing wound into a roll shape is attachable. The roll attaching portion, the tension bar, and the roll attaching portion are disposed on a back side of the supporting frame and are disposed in such order from a supporting frame side; and a medium after printing is wound into a roll shape on a front side of the supporting frame. The tension applying mechanism includes a frame having a guide groove for guiding the tension bar in a vertical direction.

A device (2) includes a media roll (4) to output a print medium (M) in a forward direction (26) and a wiper roll (6) to contact the surface of the print medium (M) at a rotation speed to cause friction on the print medium (M). The device (2) may determine a radius (r2) of the media roll (4) outputting the print medium (M) and, based on this radius (r2), adapt parameters such as the rotation speed of the wiper roll and a back tension (T2) exerted by the media roll (4) on the print medium (M) so as to control the friction caused by the wiper roll (6) on the print medium (M).

A printing apparatus includes a transporting unit that transports a printing medium, a transporting unit encoder that outputs a movement amount information indicating a movement amount of the printing medium, a medium winding unit disposed downstream of the guide member with respect to the transporting unit and winds the printing medium, a tension applying unit including a tension bar that presses the printing medium at a location between the transporting unit and the medium winding unit while the tension bar is moving between an upper limit position and a lower limit position and applies tension to the printing medium, a tension applying unit encoder that outputs a rod member location information indicating a position of the tension bar, and a control unit that determines a movement state of the printing medium at the tension applying unit, based on the movement amount information and the rod member location information.

Provided is a recording device including a conveying portion configured to convey a medium in a conveying direction, a recording unit configured to record on the medium conveyed in the conveying direction, a guiding portion disposed further downstream in the conveying direction than the recording portion and configured to change the conveying direction while guiding conveyance of the medium, a winding portion disposed further downstream in the conveying direction than the guiding portion and configured to wind the medium, and a heating portion configured to heat the medium disposed between the recording portion and the winding portion in the conveying direction, heat the guiding portion, and heat the winding portion.

The present invention refers to a plant (1) for printing a fibrous material (T). The printing plant (1) comprises: a station (14) for supplying a fibrous material configured for supplying the fibrous material along a predetermined operative path, a treating station (10) configured for treating the fibrous material with a treatment composition by applying the composition itself on a first side (T1) of the fibrous material (T); and a printing station (6) configured for ink-printing at least part of a second side (T2) of the fibrous material (T) opposite to the first side (T1). Moreover, the present invention refers to a process of printing a fibrous material.

A medium wind-up device is provided to suppress causing a wrinkle at a time of winding a medium, and also suppress a fluctuation of a winding position. The medium wind-up device includes: a tension roller that presses a medium, which is belt-shaped and transferred in a transfer direction that is predetermined, in order to provide the medium with a tension; a reversing roller that reverses the medium pressed by the tension roller, and the reversing roller being rotatable so as to follow a move of the medium; a loading mechanism that is capable of placing a load against a rotation of the reversing roller; and a wind-up portion that winds up the medium reversed by the reversing roller.

The printing apparatus includes a supply section that supports a plurality of rolls into which roll-paper strips are wound and supplies the roll-paper strips, a transport section that applies respective transporting forces to the supplied roll-paper strips and transports the roll-paper strips, a printing section that performs printing onto the transported roll-paper strips, and a tension-imparting section that individually imparts respective tensile forces to a plurality of roll-paper strips against the transporting forces.

A controller: generates a first corrected pulse signal by correcting a received first pulse signal or generate a second corrected pulse signal by correcting a received second pulse signal, based on a difference value between a first rotation cycle of a first roller and a second rotation cycle of a second roller such that a difference between a first pulse cycle of the received first pulse signal and a second pulse cycle of the received second pulse signal is reduced; upon generating the first corrected pulse signal, controls first print timings in respective first print mechanisms of a first printer based on the generated first corrected pulse signal; and upon generating the second corrected pulse signal, controls second print timings in respective second print mechanisms of a second printer based on the generated second corrected pulse signal.

A printer includes a mainframe including a front face part that has an opening through which a recording medium passes; a guide unit connected to the mainframe on a first side of the front face part; a printer mechanism unit configured to perform printing on the recording medium, and connected to the mainframe on a second side of the front face part opposite to the first side thereof; an arm unit having a first end connected to the mainframe; and a shaft unit configured to hold a roll of the recording medium, and connected to a second end of the arm unit, wherein the guide unit is configured to guide the recording medium so as to feed the recording medium to the printer mechanism unit through the opening of the front face part of the mainframe.

A label printer includes: a feed control lever configured to rotate following a change in length of a roll paper between a transport roller pair and a feed roller pair, a first detector configured to detect a rotational angle of the feed control lever, a second detector configured to detect the rotational angle of the feed control lever, and a printing control unit, wherein the transport roller pair has a first mode in which the roll paper is transported at a first transport speed, and a second mode in which the roll paper is transported at a second transport speed that is slower than the first transport speed, the printing control unit is configured to control the feed roller pair based on the first detector in the first mode, and is configured to control the feed roller pair based on the second detector in the second mode.
