A hand held printing device is disclosed that tracks its motion and prints an image based on its sensed position. The printing device includes a controller, a position sensor, a housing, a display, and a user interface. The display is pivotable between an open position, in which it uncovers the user interface, and a closed position in which the user interface is covered. The printing device further comprises a recessed bottom surface to prevent smearing of ink and an alignment mechanism that allows a user to precisely align a printed image. The alignment mechanism includes a reference indicator located on the housing in close proximity to a target surface and a correlating reference indicator located on the display.
