Abstract: In a printer with a multiple continuous-sheet processing capability, a first pusher tractor unit and a second pusher tractor unit disposed above the first feed continuous sheets from the front of the printer to a printing line along substantially straight paths and both are accessible from the front of the printer for the loading of continuous sheets into the tractors, the second simply by the opening of an anti-noise cover and the first by the tilting of the second unit about a pivot axis on the opposite side of the paths to the second unit in the position above the first.

Abstract: A multicolor inked ribbon cartridge for an impact serial printer comprising a ribbon housing body and two arms protruding from such body to allow the interposition of a ribbon portion between a printing head and a printing support for the whole length of the platen when the cartridge is rotatably attached to the frame of an impact serial printer by means of two lateral cylindrically-shaped projections provided on the body of a cartridge thus permitting rotation of the body around a common axis of said cylindrical projections, parallel to the platen. The cartridge rotation around such axis and therefore the positioning of a suitable multicolor band between the printing head and printing support is assured by a cam actuated by a motor and interacting with the body of such cartridge. The cartridge is further provided with a string made tight between the ends of its arms upon the multicolor ribbon portion which is interposed between the head and printing support.
