In 1843, Pann established a printing press inside the Olteni Church, which published works by several authors of his day, as well as a long series of almanacs. He later confessed that this enterprise had drained his economies, and that he had relied on support from various benefactors. Upon Neofit's request, he also began the translation of various religious texts. Pann's comprehensive and innovative textbook for music, "Bazul teoretic şi practic al muzicii bisericeşti" ("The Theoretical and Practical Basis of Church music or the Melodic Grammar"), was officially endorsed by the Metropolitan and taught at the seminary after 1845 and became a template for similar works; in addition, his printing shop sold cheap copies of popular novels, such as the "Alexander Romance", the "Book of 1001 Nights", the "Book of Til Owl-Mirror", and the "Story of Genevieve of Brabant". In March 1847, Anton Pann authored an account of the Great Fire of Bucharest. During the latter disaster, his printing shop was heavily damaged, and he was only able to salvage the presses. He resumed his activities only in 1849, when he moved the business to a house owned by Catinca Pann on Taurului Street.
