Johannes Gutenberg established a movable-type printing workshop in Mainz by 1450, financing operations through loans from Arnold Gelthus and Johannes Fust. The enterprise produced the 42-line Bible, completed in 1455, alongside other texts. A subsequent lawsuit resulted in Fust gaining control of the workshop, leaving Gutenberg effectively bankrupt.

Background and detail
Workshop Establishment and Early Financing. Gutenberg returned to Mainz in 1448 and secured a loan from his brother-in-law Arnold Gelthus, possibly for a printing press or related paraphernalia. By 1450, the press was operational, producing a German poem. To fund the ambitious Bible project, Gutenberg borrowed 800 guilders from Johannes Fust, commencing work in 1452.
Bible Production and Early Outputs. Between 1450 and 1455, Gutenberg printed various texts, including the 31-line Indulgence and editions of Aelius Donatus's grammar that may have been printed by him. The 42-line Bible, the earliest major book printed in Europe with mass-produced metal movable type, was completed in 1455. A letter from March 1455 reports that pages were displayed in Frankfurt to promote the edition.
The Fust Lawsuit and Bankruptcy. A legal document from November 1455 recorded a partnership dispute where Fust claimed Gutenberg misused funds intended for the 'project of the books.' The court ruled in Fust's favor, granting him control of the workshop. Gutenberg was left effectively bankrupt.
