The present printer is adapted to be easily equipped with removable and interchangeable paper feed modules of several different types. Each of the paper feed modules is specifically adapted to feed a particular type of paper through the printer and each is easily replaceable by the purchaser of the printer to be used for feeding a specific type of paper therethrough. The printer is provided with a main frame including a pair of side support members and an elongate platen extends between the side support members and is fixed at opposite ends thereto. Three different types of removable and interchangeable paper feed modules are illustrated in the present application and each includes a pair of elongated end plates with a paper moving mechanism supported intermediate the elongated end plates. The end plates are each provided with a pivoted mounting member adapted to engage a guide slot in the main frame side support members and a mounting notch is provided in the midportion of each of the end plates to swing into clamping engagement with the platen when the elongated end plates are pivoted about the pivotal axis of the mounting members so that the removable paper feed module may be inserted into the working region of the printer and on the side of the platen opposite the printhead and pivoted toward the printhead to bring the clamping notch into clamping engagement with the platen.
