In order to produce this type of printing in a simultaneous way, the user (5), via internet or intranet (8), accesses the system through a covenant and/or directly (9) in addition to his/her registered data (4), which are identified with the name, identity registration number, social security number (or other ID), computer's IP address from where the reader accesses the system, date, hour (6), which are stored in a database (10) in order to formalize the printing requisition (11) of the content (3) from a book or digital media. This content (3) from books or from a digitalized media, stored in a proper database (12) is loaded in a page (13) in the system's memory, and at the same time, the database (10), with the registered data (4) from the user (5) and the others (publishing company and computer), transcribes the data in another page (14) in the system's memory so that in the sequence, they are to be merged through a programme, “software”, integrating then the content (3) with the registered data (4) in undertone, to result, in one sole stage, a unique document (15), with the personal data from the user (5) and others (publishing company and computer) in undertone like a watermark at the bottom of the document (15) and over this watermark, the book content (3).
