    • Printing apparatus on a (not shown) print support comprising:
      - A print head (13) to print on said print support a print material;
      - A feed device (11) to feed said print material to said print head (13), and
      - A recirculating unit (15) to generate a recirculation of said print material through said print head (13), said recirculating unit (15) in its turn comprising:
      a. A first container (14) of said print material (11) placed upstream of said print head (13);
      b. A second container (18) of said print material, placed downstream of said print head (13);
      c. A first recirculating sub-unit (16) to generate a first flow of said print material from said first container (14) to said print head (13) and said second container (18);
      d. A second recirculating sub-unit (17) to transfer said print material from said second container (18) to said first container (14),
      characterized in that
