Printing apparatus
The printing apparatus includes a ribbon laid between spools, and DC motors for rotating these spools. A CPU drives the motor without tension, calculates the rotation velocity of the motor based on the rotation amount of the motor, applies the calculated rotation velocity and supplies current in driving the motor, by calculating a drive current for providing the DC motor with a same rotation velocity as a rotation velocity of a reference DC motor based on a difference between a rotation speed of the DC motor in driving the DC motor at a predetermined supply current in a state in which the ribbon is broken, or the ribbon is separated from the supply spool, and a rotational speed of the reference DC motor in driving the reference DC motor at the predetermined supply current, and controls the motor driver to supply the calculated drive current.
Media processing device with enhanced media and ribbon loading and unloading features
An example media processing device includes a base; a lid hingedly attached to the base movable relative to the base between a closed position and an open position, wherein a cavity is defined between the base and the lid; a printhead assembly attached to the lid; and a ribbon positioning assembly disposed within the cavity that is pivotably attached to at least one of the lid or the base wherein the ribbon positioning assembly is configured to move between a printing position when the lid is in the closed position, and an accessible position when the lid is in the open position, wherein the ribbon positioning assembly comprises: at least one cartridge channel configured to receive therein a ribbon cartridge; and at least one printhead assembly channel configured to guide the printhead assembly along the printhead assembly channel in response to the lid being moved between the open position to the closed position.

ADAPTIVE RIBBON SPEED CONTROL SYSTEMS AND METHODS
Systems and methods related to adaptive ribbon speed control for a line matrix impact printer are provided. A ribbon cartridge includes a ribbon configured to be driven at a ribbon speed, and a ribbon gear configured to rotate with movement of the ribbon. The ribbon includes a ribbon joint patch detectable via a first sensor to determine a first ribbon speed of the ribbon. Rotation of the ribbon gear is detectable via a second sensor to determine a second ribbon speed of the ribbon. A target ribbon speed is determined based on at least one print job characteristic. A current ribbon speed is determined based on the first ribbon speed and the second ribbon speed. The ribbon speed is adjusted based on a difference between the current ribbon speed and the target ribbon speed. Associated systems and methods are also provided.

Media processing device with enhanced media and ribbon loading and unloading features
A device for processing media may include a system and method for loading and unloading consumable supplies of a media processing device, and more particularly, a system and method for providing a compact form factor media processing device which provides convenient access to the replaceable components of the media processing device. A media processing device may include a base and a lid hingedly attached to the base, moveable between a closed position in which the lid is secured to the base, and an open position. A cavity may be defined between the lid and the base, where the cavity is inaccessible when the lid is in the closed position and the cavity is accessible when the lid is in the open position. The media processing device may include a ribbon positioning assembly disposed within the cavity.
Printer
A printing apparatus includes a feed side roll, a winding roller, a driver, a detector, a printer, a conveyance roller, and an adjuster. The feed side roll includes an ink ribbon wound on a feeding roller. The driver rotates the winding roller in a direction of winding the ink ribbon. The detector detects a change in a tension of the ink ribbon being wound. The printer prints on a print medium via the ink ribbon stretched in a tense state between a collection side roll where the ink ribbon is wound and the feed side roll. The conveyance roller winds the ink ribbon between the collection side roll and the printer. The adjuster adjusts a torque for rotating the winding roller by the driver based on detection results by the detector to keep a tension of the ink ribbon passing through the printer constant.
