Abstract: Plotter for digital printing, including



a main structure, arranged to be rested on a support surface;
a printing head, associated with the main structure and movable along a substantially horizontal transverse direction, for a predetermined stroke in alternating and opposite directions;
a transport device, arranged to lead a material to be printed forwards along a longitudinal direction which is substantially horizontal and perpendicular to the transverse direction.




The transport device is removably associated with the main structure by means of connection means. The connection means is arranged to assume an operating configuration, in which the transport device is connected to the main structure in a substantially rigid manner with respect to direct movements along the longitudinal direction and with respect to direct movements along the transverse direction, and a non-operating configuration, in which the transport device is movable with respect to the main structure.

Abstract: A system and method for enhanced speed thermal printing has a drive roller for contacting thermochromic medal to a thermal printhead. The drive roller includes a cam which causes the drive roller to decelerate as it approaches the printhead such that contact with the thermal printhead and the thermochromic media is at a highest force point. The drive roller accelerates as it is pulled back from the printhead prior to a next printing cycle.

Abstract: A printer is provided with a platen support member, a platen, and a positioning portion. The platen support member supports the platen. The platen includes a rear engaging portion. The positioning portion includes a rear roller. The rear roller is provided at the platen support member, and can move in the front-rear direction with respect to the platen support member. The rear roller engages with the rear engaging portion in a state in which the platen is supported by the platen support member. The positioning portion positions the platen at a prescribed printing position in the front-rear direction, by the rear roller moving forward in a state in which the rear engaging portion is engaged with the rear roller.

Abstract: A device for printing flat packages fed individually to a printing unit of a franking machine, pass the printing unit on one side and are guided on a side edge in the conveying direction, including a conveying apparatus which grips the packages at a front end and, by a guide plate forms a conveying plane of a conveying gap with an opposite conveying unit of the conveying apparatus. In the conveying direction, the conveying unit has two endless drawing devices next to each other which circulate a common axle on deflecting rollers, and the upper run of which, and the lower run of which are guided on running rollers mounted freely rotatably in pairs so as to lie opposite one another at pivotable ends of double lever arms assigned to the upper and the lower run, and supported on the inner side of the runs by spring force.
