The present subject matter discloses detection of positions of print medium for driving the print medium for printing in a printing system, in an example implementation, a motor is operated for driving the print medium, at a first specific speed, along a media-path in the printing system. After a first specific number of rotations of the motor, it is detected, based on identification of a torque change event, that the print medium at a de-skew position in the media-path. At the de-skew position a leading edge of the print medium is at a de-skew unit of the printing system and the torque change event is indicative of a deviation in a current operating torque of the motor from a standard operating torque of the motor.

A printing apparatus includes a drying unit that includes a bring-in port where a medium is brought in and a bring-out port where the medium is brought out, and dries ink applied onto the medium, and in a case in which printing is temporarily stopped and a predetermined maintenance work is performed, the medium is transported in a transporting direction which is a direction toward the bring-out port from the bring-in port in a maintenance work period from starting of the maintenance work to finishing of the maintenance work or in a partial period of the maintenance work period.

A print device includes a head, a medium holding portion, an opening/closing cover, a feed path, a sensor, a window portion, and a blocking wall. The medium holding portion holds the medium and open to allow the medium to be taken out and put in. The opening/closing cover opens and closes an opening in the medium holding portion. The feed path extends from the medium holding portion toward the head and feeding the medium. The sensor is provided in the feed path. The window portion is provided in a position corresponding to between the sensor and the head, in a wall portion of the case, and allows the inside of the case to be seen from outside. The blocking wall is provided between the sensor and the window portion, and blocks a light coming in through the window portion toward the sensor.

A printer includes a head unit and a platen unit. The head unit includes a print head. The platen unit includes a platen roller, a support, and a guide roller. The platen roller is rotatably supported on the support and configured to rotate to convey recording sheet. The guide roller includes a roller part, and the roller part is configured to rotate in contact with the recording sheet as the recording sheet is conveyed.

In an example of the disclosure, power of a first light beam emitted across a web media along a length of the roller is measured utilizing a first optical transmitter and first optical receiver pair situated adjacent to a roller. Power of a second light beam emitted across a length of the roller is measured utilizing a second optical transmitter and second optical receiver pair situated adjacent to the roller. A media height non-uniformity is identified based upon of the measurement of the power of the first light beam and the measurement of the power of the second light beam.

There is provided a printing apparatus including: a holder configured such that a print medium wound in a roll shape is to be attached to the holder; a printer configured to perform printing on the print medium; a memory configured to store print condition information indicating a print condition regarding the print medium attached to the holder; and a controller configured to execute a processing of printing the print condition information on a condition print area of a single line or a plurality of lines on the print medium by using the printer.

A printing device 1 includes a print section 8 for printing on a continuous medium M, a pair of holding sections 3 each having an insertion section 15 configured to be inserted into one of a first winding core of the wound medium M or a second winding core for winding the medium M from an outer side in an extending direction of the winding core, and a support section 19 for supporting the holding section 3, wherein the support section 19 is disposed closer to the print section 8 than the holding section 3 in a first direction, which is a direction from the holding section 3 toward the support section 19, of directions perpendicular to the extending direction of the winding core. By adopting the printing device 1 having such a configuration, it is possible to configure the printing device 1 to be lowered.

A printer includes: a body with a set of interior walls defining a media enclosure configured to receive a media cartridge, and a latch recess in one of the interior walls, including a retaining surface, and a ramp surface; a lid rotatably coupled to the body and movable between open and closed positions; and a latch movably supported by the lid between a locked position and an unlocked position, the latch including: a bias member biasing the latch towards the locked position, a hook surface configured to engage the retaining surface when the lid is closed and the latch is in the locked position, and a cam surface configured via the bias member, when the lid is closed and the latch is released to the unlocked position, to slide against the ramp surface and lift the lid to an intermediate position between the open and closed positions.

A printing apparatus includes: a roll paper container portion that accommodates roll paper formed into a roll by wrapping recording paper around a core; a transportation roller that transports the recording paper in a transportation direction; a buffering member that moves in contact with the recording paper; and a guide member that is provided upstream of the buffering member in the transportation direction and guides the core of the roll paper that is moved from an inside of the roll paper container portion to an outside.

A printing apparatus includes a printing unit; a first conveyance unit configured to convey a sheet to the printing unit while nipping the sheet; a second conveyance unit provided on a downstream side of the first conveyance unit in a conveyance direction of the sheet, and configured to convey the sheet while nipping the sheet; a third conveyance unit provided on a downstream side of the second conveyance unit in the conveyance direction, and configured to convey the sheet while nipping the sheet; and a switching unit configured to switch between a nip state of the second conveyance unit and a released state in which the nip state is released. When the sheet is conveyed by the third conveyance unit, the switching unit switches between the nip state and the released state in accordance with a length of the sheet.
