Gauthier took over the family printing business, founded by his father, on his brother Ghileyn's death in 1574. Over the course of his fifty-two-year career he printed over 300 titles. Under the Calvinist regime he printed Calvinist books, most importantly a Dutch abridgement of Calvin'sInstitutes of the Christian Religion. From 1585 he printed Catholic books. Much of his work, however, was legal printing for the City of Ghent and the Council of Flanders, and other secular material. He died in late 1626. His widow ran the business from 1626 to 1631, when their son, Servais Manilius, came into his inheritance.
