ABSTRACT:
Systems, apparatuses, and methods for a handheld image translation device configured to detect an edge of a target print medium to prevent unintended deposition of a printing substance are described herein. The handheld image translation device, which may be a printing device, may include a print head, a position module, and a print module. The print head may be configured to deposit one or more printing substances onto a first surface such as a target print surface. The position module may be configured to receive data from navigation sensors indicating a first surface characteristic of the first surface, and to determine whether at least a portion of the print head is positioned over a second surface having a second surface characteristic different from the first characteristic, wherein the determination is made by detecting a characteristic other than the first surface characteristic as indicated by data received from the navigation sensors.
