As a member of a patrician family, Gutenberg likely had access to some financial resources early in his life through inheritance and family wealth. This likely supported his initial experiments and ventures.

To sustain himself in Strasbourg, Gutenberg was involved in various trades, including metalworking and jewelry making. These activities provided him with income and practical skills applicable to his later printing experiments.

The investment made by Dritzehn, Heilmann, and Frieburg represented a significant influx of capital, allowing Gutenberg to pursue more ambitious projects than he could have financed alone.

The two loans from Johannes Fust, totaling 1600 guilders, were essential for Gutenberg's continued development of the printing press and the production of the Gutenberg Bible. These loans highlight the high costs associated with early printing technology.

The lawsuit by Fust and Gutenberg's subsequent loss of the printing press marked a severe financial setback. He lost not only the equipment but also the potential profits from his invention.

The position granted by the Archbishop of Mainz provided some degree of financial security in his final years. While not restoring him to his previous prosperity, the stipend offered a stable income and recognition for his achievements.
