A product history management apparatus issues to label issuing apparatuses identification information to be printed on a label affixed on a product produced in production steps from raw material production to final product production. An identification information receiving device receives from a label issuing apparatus associated with one of the production steps information printed on a label affixed in a production step immediately preceding the one production step. An identification information transmitting device issues new identification information relative to the received identification information and transmits to the label issuing apparatus associated with the one production step the issued identification information. An identification information storage device stores the received identification information in the production step immediately preceding the one production step in association with the issued and transmitted new identification information.

A line thermal printer is assembled in a pair of side frames opposed to each other a given distance according to a given width size of a printing medium. A guide frame is sandwiched between the pair of side frames for guiding the printing medium. A platen roller unit is disposed detachably between the pair of side frames and is pivotably supported relative to the pair of side frames. A thermal head unit is detachably engaged relative to the pair of side frames in opposed relation to the platen roller unit. A head cover plate is disposed between the pair of side frames to cover the thermal head unit and is placeable in either of an open position and a closed position relative to the pair of side frames. A drive unit is detachably mounted on an outer face of one of the side frames for driving the platen roller.
