Printer's devil

Definition and stakes

Various,  Devil Stories (1921)

“ In the infernal economy, where a strict division of labour prevails, the printer's devil is the librarian of hell. The books over which he has charge must be as numerous as the sands on the sea-shore. For nearly every book written without priestly command was associated in the good old days with the devil. The assertion that Satan hates nothing so much as writing or printer's ink apparently is a very great calumny. He has often even been accused of stealing manuscripts in order to prevent their publication. The prince of darkness naturally rather shuns than courts inquiry. ”

Samuel Grant Oliphant,  Queer questions and ready replies (1886)

“ What was the origin of the expression “Printer’s Devil”?
Aldus Manutius (1449–1515) , the celebrated Venetian printer and publisher, had a small black slave whom the superstitious believed to be an emissary of Satan. To satisfy the curious, one day he said publicly in church, “I, Aldus Manutius, printer to the Holy Church, have this day made public exposure of the printer’s devil. All who think he is not flesh and blood, come and pinch him.” Hence in Venice arose the somewhat curious sobriquet of the “printer’s devil.”
