We propose oblivious printing, a novel approach to document printing in which a set of printers can cooperate to print a secret message-in human or machine readable form-without learning the message. We present multi-party protocols for obliviously printing a secret in three settings: obliviously printing the contents of a ciphertext, obliviously printing a randomized message, and generating and obliviously printing a DSA/Elgamal keypair. We propose an approach to improving the legibility of
