Abstract: A spherically-shaped mechanical interface is configured for coupling a glasses arm with a frame. The spherically-shaped mechanical interface comprises a surface having a generally spherical curvature and at least two holes extending through the surface. The surface is configured to be secured to a portion of a glasses arm by a fastener that is received along a first axis through a first hole of the at least two holes. The surface is configured to be secured to the portion of the glasses arm by another fastener that is received along a second axis, distinct from the first axis, through a second hole of the at least two holes.

Abstract: Example systems are disclosed for printing an image. In one example, the system includes a printhead assembly including a plurality of printheads to deposit printing fluid on a print media as the printhead assembly is moved across the print media along an arcuate path. In addition, the system includes a controller assembly communicatively coupled to the printhead assembly, wherein the controller assembly is to adjust a timing of printing fluid deposition onto the print media from the plurality of printheads based on relative positions and orientations of the printheads along the arcuate path.

Abstract: In some examples, the disclosure describes a device that includes a moveable carriage, a chimney coupled to a first side of the moveable carriage to be positioned to receive a print substance when the moveable carriage is in a particular position, and a reservoir coupled to a second side of the moveable carriage to collect the print substance received at the chimney.

Abstract: In one example in accordance with the present disclosure, a lighting assembly for a handheld printing system is described. The lighting assembly includes a light source to emit a beam of light onto a surface to generate a light box which indicates a print area on the surface to receive printed content as the handheld printing system is moved. The lighting assembly also includes a reflective surface to reflect the beam of light towards a molded opening and the molded opening through which the beam of light passes. The lighting assembly also includes a clear cover over the molded opening.

Abstract: According to examples, an apparatus may include a tracking sensor, a delivery device and a controller. The controller may receive an input indicative of the apparatus being aligned to an alignment location, determine, based on input from the tracking sensor, that the apparatus has moved a predefined distance or past the predefined distance in a first direction from the alignment location, and based on a determination that the apparatus has been moved the predefined distance or past the predefined distance, cause a first feedback to be outputted to instruct a user to move the apparatus in a second direction. The controller may also, as the apparatus is moved in the second direction, cause the delivery device to generate an image that has an intended justification with respect to the alignment location.

Abstract: Present examples relate to fluid ejection peripherals for, non-limiting example, ink jet peripherals. More specifically, but without limitation, present examples relate to caps for fluid ejection peripherals which may be locked or unlocked relative to the peripheral device.

Abstract: In some examples, velocity and torque based media motor control may include ascertaining a velocity and torque for a feed roller motor associated with a feed roller, and ascertaining a velocity and torque for a drive roller motor associated with a drive roller that is to receive media from the feed roller. Further, velocity and torque based media motor control may include determining whether the torque for the drive roller motor is greater than a torque target. In response to a determination that the torque for the drive roller motor is greater than the torque target, the torque for the drive roller motor may be reduced to the torque target, and the torque for the drive roller motor may be maintained at the torque target.

Abstract: The direction and distance for traversal by a media loaded into the printer is determined. A skew to be induced in a position of the media relative to a media feed direction axis is also determined. A scheme of motion for the rollers is selected and respective speeds for the first roller and the second roller are calculated. The first roller and the second roller are caused to be rotated at the respective speeds such that the skew is induced in the position of the media relative to the media feed direction.
