Digital printing device, comprising: a fixed frame; a support portion; at least one printing module that is attached to said support portion and equipped with at least one print head, whose nozzle plate faces, in use, a printing area underlying the printing module; at least one collection member so shaped at the top as to define a collection tank;wherein said digital printing device is arranged to print onto a printing medium that is relatively movable with respect to the fixed frame through said printing area in an advancement direction; wherein said collection member and said printing module are relatively movable with respect to each other so as to be able to take at least two alternative configurations, among which: at least one collection configuration, wherein said collection member is located below said nozzle plate, the collection tank being arranged to collect liquids dropping therefrom; and a printing configuration in which said collection member is side by side along said advancement direction with a lower portion of the printing module, above the plane on which the nozzle plate lies, wherein said printing modules are a plurality, said collection members are a corresponding plurality, and each printing module is equipped with a respective collection member; wherein said printing modules are subsequently aligned along the advancement direction; in the printing configuration, each collection member is shifted toward the same side along the advancement direction with respect to its printing module, each collection member except for a first one being housed in a respective recess obtained between end portions of subsequent printing modules; characterized in that said collection member has at the bottom a suction opening; wherein, in the printing configuration, said suction opening is positioned downstream, with reference to the advancement direction of the printing medium, with respect to the nozzle plate, to suck excess ink particles released by the nozzle plate above the printing medium. a fixed frame;
