Court case

Some time in 1456, there was a dispute between Gutenberg and Fust, in which Fust demanded his money back, and accused Gutenberg of misusing the funds. Gutenberg's two rounds of financing from Fust, totaling 1,600 guilders at 6% interest, now amounted to 2,026 guilders. Fust sued at the archbishop's court. A legal document, from November 1455, records that there was a partnership for a "project of the books," the funds for which Gutenberg had used for other purposes, according to Fust. The court decided in favor of Fust, giving him control over the Bible printing workshop.

Thus, Gutenberg was effectively bankrupt, but it appears he retained, or restarted, a printing shop and participated in the printing of a Bible in the town of Bamberg around 1459, for which he seems at least to have supplied the type. But since his printed books never carry his name or a date, it is difficult to be certain. It is possible the large Catholicon dictionary, printed in Mainz in 1460 or later, was executed in his workshop, but there has been considerable scholarly debate.

Meanwhile, the Fust–Schöffer shop was the first in Europe to bring out a book with the printer's name and date, the Mainz Psalter of August 1457, and while proclaiming the mechanical process by which it had been produced, it made no mention of Gutenberg.
