Abstract: A transaction printing device having a base with a width dimension of no greater than about 6.5 inches includes a printhead cartridge stall coupled to the base and mounted for rectilinear movement along a path of travel along the width dimension of the printing device. The stall supports from below a printhead cartridge to facilitate the ejecting of ink onto a transaction receipt having a width dimension of about 3 inches. The printhead cartridge has a generally box like shape with a front wall member having an integrally connected outwardly projecting for defining a pair of printhead linear translation reversing spaces adjacent the front wall member to facilitate reversing the linear translation of the printhead cartridge to print the transaction receipt. The method of printing the transaction receipt includes moving the printhead cartridge and a printhead wiper relative to one another in one direction along a rectilinear path of travel of substantially less than 6.5 inches to eject ink onto a portion of roll paper to facilitate the forming of the transaction receipt and to clean the printhead with the wiper. The printhead cartridge and the printhead wiper are then moved relative to one another in an opposite direction along the rectilinear path of travel to eject ink onto another portion of the roll paper to further facilitate the forming of the transaction receipt and to cleaning the printhead with the wiper. The moving of the printhead cartridge is repeated a sufficient number of times until the transaction receipt is printed.
