DETAILED DESCRIPTION OF EMBODIMENTS

(8) With reference firstly to FIG. 1 of the drawings, a schematic of a state of the art printing device is shown. The printer of FIG. 1 shows a separate ink module 10. It can be observed in FIG. 1 that the ink module 10 is independent from the other modules of the printer of FIG. 1, namely a printing module 11 and a drying module 12. This state of the art configuration provides a single ink module 10 that provides ink to the imaging device, e.g. print head, of the printer of FIG. 1. This configuration has the implication that a complete catalog of inks, needed to fulfill the needs of a plurality of printing modes, must be loaded into the ink module 10.

(9) Alternative state of the art printing devices are known. Alternative state of the art configurations provide an alternative configuration of an ink module to provide ink to the imaging device, e.g. print head, of a printer. It has the characteristic that all the ink tanks needed are provided inside the printing module. This configuration also has the characteristic that a complete catalog of inks, needed to fulfill the needs of a plurality of printing modes, must be loaded into the ink tanks of the printing module.

(10) With reference to FIG. 2 of the drawings, a schematic view of one of the possible configurations of the printer of the present invention is shown.

(11) The configuration shown in FIG. 2 is characterized by the presence of a printing module comprising a first imaging device operatively connected to a first ink supply, and a first media transport mechanism. In the configuration shown in FIG. 2 there is no second imaging device in the slot for accommodating an optional second imaging device. As it can be observed in FIG. 2, the printing module comprises an ink supply line and a first ink inlet port connecting the slot for accommodating an optional second imaging device to the exterior of the printing module. In a particular embodiment, the first ink supply in the printing module can be used for storing black ink, as well as other liquids required by the printer as maintenance liquids and/or primer.

(12) As it can be observed in FIG. 2, the modularity provided by the present invention allows providing a simple configuration which can be expanded for a plurality of other printing modes by adding an additional second imaging device in the printing module, and an additional ink supply module, as it is shown below with reference to FIG. 3.

(13) In the case, for example, of a black and white printing mode, the modularity provided by the present invention allows combining the printing module of the represent invention with an ink supply module that comprises no ink supply, thereby providing a customizable printer whose complexity can be easily adapted to the printing mode needed.

(14) With reference to FIG. 3 of the drawings, a schematic view of a configuration of the printer of the present invention is shown. The printer of FIG. 3 shows a first ink supply in the printing module and a second ink supply in an ink supply module.

(15) In the configuration shown in FIG. 3 the first ink supply is operatively connected to the first imaging device of the printer of FIG. 3 while the second ink supply is operatively connected to the second imaging device of the printer of FIG. 3. In a particular configuration, the first modular ink supply may comprise the black ink needed for black and white mode as well as any other fluids required by the printer of the present invention. The second ink supply may comprise the plurality of color inks needed for full color mode by the printer of the present invention.

(16) In the configuration shown in FIG. 3, the second imaging device receives ink through a first ink inlet port. In turn, said first ink inlet port is configured such that in operation an ink can flow from the second ink supply device comprised in the ink supply module to the second imaging device comprised in the printing module through said first ink inlet port via an ink supply line. The configuration shown in FIG. 3 profits from the modularity provided by the present invention by providing a printer for a plurality of printing modes simply by introducing an additional ink supply module comprising a second ink supply. Additionally, the printer configuration in FIG. 3 comprises a slot for accommodating an optional drying/fixation apparatus which allows increasing the drying capabilities for particular printing modes.

(17) With reference to FIG. 4 of the drawings, a schematic view of the printer of the present invention for a black and white printing mode is shown. The printer of FIG. 4 shows a first ink supply and a second ink supply.

(18) It should be noted that the printer of FIG. 4 shows a similar configuration presented in FIG. 3 but with the different modules ordered from right to left.

(19) The configuration shown in FIG. 4 is characterized by the presence of said first ink supply and second ink supply, wherein the first ink supply is operatively connected to the first imaging device of the printing module 40 of FIG. 4 while the second ink supply is operatively connected to the second imaging device of the printing module 40 of FIG. 4. In the configuration shown in FIG. 4, the second imaging device receives ink through a first ink inlet port. In turn, said first ink inlet port is configured such that in operation an ink can flow from the second ink supply device comprised in the ink supply module 41 to the second imaging device comprised in the printing module 40 through said first ink inlet port.

(20) The configuration shown in FIG. 4 allows leaving out the second ink supply device, thereby providing the advantage that depending upon the printing mode selected, a simpler configuration can be provided. In the case, for example, of a black and white printing mode, the modularity provided by the present invention allows skipping the presence of ink in the second ink supply device, thereby providing a customizable printer whose complexity can be easily adapted to the printing mode needed.
