The ink jet printer comprises a printhead () movable in front of a printing medium () and provided with an ink cartridge () integral with it; the cartridge is filled with ink from a main, high capacity tank (), which is connected at intervals to the cartridge () by means of a capillary element. During each connection, the capillary element () is brought into contact with the sponge () inside the cartridge, while a peristaltic pump () mounted integral upon the main tank provides a pressure suitable for generating a sufficient flow of ink to refill the cartridge () in a short time frame. To perform the refilling, the cartridge is brought at the end of its stroke into a service station () mounted on the body of the main tank (), which is moved against the cartridge by means of a motor-driven linkage, controlled by a refilling management programme, in response to the signals of a cartridge ink level sensor.

In a receipt printer (), suitable for printing on a paper ribbon of different widths, wound on a roll () arranged in a seat () in the printer, a wall is provided for the lateral positioning () of the roll of paper () in its seat, to keep the paper ribbons, or the respective rolls () of at least two different widths in the proper printing position, independently of the width of the ribbon; the positioning wall () is arranged inside the seat () of the roll of paper, with a first surface () facing a side (') of the same roll (). When the roll () is replaced with another roll () of different width, the positioning wall () is repositioned in the seat (), rotated through 180&#xb0;, to laterally retain the new roll () with the second face (), opposite the first face (); the positioning wall () is suitable for being attached to the walls () of the seat () through flat tabs (), protruding beyond the edge () of the positioning wall (); the positioning tabs () are all arranged staggered on one side (), with respect to the median plane of the wall () and flush with one () of the two faces of the positioning wall () and are also suitable for engaging corresponding pairs of slots () formed in the walls of the seat ().
