Sixtus Riessinger (1440/45-post 1505),[1] also called Xistus Reissinger or Rüssinger, was a German printer active in Italy.
Reissinger was born between 1440 and 1445 in Sulz am Neckar in the Holy Roman Empire.
Before leaving for Rome, he is thought to have worked in Strasbourg in Heinrich Eggestein’s printing shop.
During the 1467–1470 years Riessinger became a prominent printer in Rome, publishing at least ten books, among them the possible editio princeps of Jerome’s letters and tractates.
The issue is controversial, since others have often put first Arnold Pannartz and Konrad Sweynheim’s edition.
