Abstract:
1. A method for operating a printing apparatus that is attachable to a mobile phone, the method comprising: mechanically attaching the printing apparatus to the mobile phone; receiving, by the printing apparatus, image data from the mobile phone; capturing, by a navigation sensor of the printing apparatus, first navigational measurements of a first portion of a medium while the printing apparatus is placed on the medium, wherein the first navigational measurements of the first portion of the medium comprises one or more images of the first portion of the medium; capturing, by an optical imaging sensor of the printing apparatus, a first plurality of surface images of the first portion of the medium while the printing apparatus is placed on the medium; based at least in part on the first navigational measurements, determining a position of the printing apparatus relative to a first reference point; based on the first plurality of surface images, calibrating the determined position of the printing apparatus relative to the first reference point, wherein calibrating the determined position of the printing apparatus relative to the first reference point further comprises while the printing apparatus is mechanically attached to the mobile phone and based on (i) the image data and (ii) the determined position of the printing apparatus as calibrated, depositing, by the printing apparatus, a printing substance on the medium; and transmitting, by the printing apparatus to the mobile phone, an operating status associated with the printing apparatus, wherein depositing the printing substance on the medium further comprises wherein the plurality of nozzles are arranged around the optical imaging sensor.
