Printing apparatus and corresponding method

A printing apparatus comprising:

• a support plane to support at least a print support;
• at least two printing groups aligned along a longitudinal axis, and each provided with at least a printing head;
• a support structure provided to support said printing groups above said support plane,
• at least a moving device to move said printing groups towards/away with respect to said support plane,
• at least two containment devices each associated with respective positioning means, wherein said positioning means are configured to selectively move, independently with respect to each other and in a parallel direction with respect to said longitudinal axis, the respective containment device at least in a first operative position in which said containment device is positioned under said at least a printing head of one of said printing groups, and in a second inactive position in which said containment device is in a position not interfering with movement of said printing group towards or away with respect to said support plane wherein said containment devices are disposed on parallel and distanced lying planes and, in the second inactive position, said containment devices are superimposed to each other.
