A print head alignment system, which includes: a) a printer having a moveable lid member and a stationary lower frame portion pivotally attached to the lid member; b) a platen having a core and a vertical center line, where the core is rotateably attached to the lower frame portion; c) a floating print head having an upper portion and a lower portion, the print head being pivotally attached to the lid member, where the print head is adapted to move in a vertical and horizontal plane; d) a nib line, which includes a row of a plurality of resistive printing elements, disposed along the print head lower portion; and e) a self-alignment assembly fixedly attached to the print head, where the assembly is adapted to contact and partially surround a portion of the platen core when the lid member is pivoted to come into contact with the lower frame portion; where when the lid member is in contact with the lower frame portion, the self-alignment assembly and the print head become positioned such that the nib line and the platen vertical center line coincide; and where the platen core includes at least one alignment groove formed thereon, each groove being adapted to receive a portion of the self-alignment assembly.
