Maciej (who also used the surname Ostrowski or Ostrogórski), a relative of Marek's, set up his own printing shop around 1526, though he worked with Marek until at least 1531 and printed all of his books. Benefiting from the patronage of Bona Sforza, Maciej was granted a privilege to print Kraków calendars, a very lucrative product. When Maciej died in 1547, his wife, Helena, took over his business until their son, Hieronim, was old enough to take over the family business. It operated under his name in 1548-1556, although Hieronim himself died in 1555. Hieronim's wife then ran the business. Kryspin Szarffenberg, from the Silesian branch of the family, settled in Zgorzelec in 1545, where he ran his own bookshop. Shortly thereafter, he moved to Wrocław where he received official approval to work as a printer and producer of woodcuts. He bought a print shop from Andrzej Winkler. At Kryspin's death in 1576, his son, Jan, took over the printing office, which he ran until 1586. The company continued for another four years until 1590, when Jan's widow, Magdalena, remarried and the business was transferred to the family of her second husband, Jerzy Baumann. The Baumann family continued to run the business until 1748.
