When his father, the illustrious printer Juan Cromberger, died in 1540, his wife, Brígida Maldonado , took over the printing press until her son Jácome was old enough to run it. In 1545 Jácome became a printer and continued with the family business.
Jácome marries the daughter of the famous printer Juan Varela de Salamanca , however, the Inquisitor General Fernando de Valdés will put many of the books printed by the Crombergers in the Index of Prohibited Books and for this and other causes Jácome ends up loaded with debts, The printing press closed in 1557 and decided to go to the Indies, where he died shortly after.
