Apparatuses and methods for locating and retrieving image data from a memory and to subsequently control nozzles of a handheld printer during a printing operation are described herein. The novel methods may include initially determining an index location of an index nozzle of a printer with respect to an image in physical image space, a version of the image being stored in a memory, and the printer having a plurality of nozzles including the index nozzle. Then, based at least in part on the determined index location, the novel methods may include calculating one or more secondary locations with respect to the image in the physical image space of one or more secondary nozzles of the plurality of nozzles. Data stored at corresponding locations of the memory may then be read based at least in part on the index and secondary locations in physical image space, the corresponding locations of the memory being associated with the index and secondary locations in physical image space. And, finally, the novel methods may include controlling the nozzles based at least in part on the reading of data at the corresponding locations of the memory to form at least a first portion of the image on a print medium.

An embodiment of a cradle has a cradle body configured to support a printing device. The cradle has first and second printer capture flanges extending from the cradle body proximate a capture end of the cradle body. The cradle has first and second biased latches extending from the cradle body between the capture end and a release end of the cradle body. The cradle has a biased release member movable between a first position and a release position. The cradle has a release linkage supported by the cradle body, the release linkage coupling the biased release member and the first and second biased latches, wherein the release linkage is structured to drive the first and second biased latches from respective locked positions to respective unlocked positions in response to movement of the biased release member from a first position to a release position.

The present disclosure relates to a portable printer and a portable printing system including: a main body in a portable form configured to accommodate a cartridge including a nozzle that prints an image by delivering a printing material to a target having a soft or hard surface; a seating part that is provided to be exposed to an outside from a lower portion of the main body to face a surface of the target and surrounds the nozzle at least partially; a roller provided at each of the front and rear of the nozzle at the lower portion of the main body, based on a direction in which the main body moves along the surface of the target to deliver the printing material to the target; and a magnetic body configured to rotate in correspondence with rotation of the roller.

A print head that discharges a liquid includes: a nozzle plate in which a nozzle aperture through which the liquid is to be discharged in an ejection direction is formed, the nozzle plate being mounted on a liquid ejection surface; a housing that accommodates at least a portion of the nozzle plate; and a handle positioned opposite the nozzle plate in the ejection direction. The handle has a greater strength than that of the housing. At least a portion of the handle is aligned with the nozzle plate in a normal direction of the nozzle plate.
