The invention provides a safe printing method, a chip, a printing consumable and a printer. The method comprises the following steps of sending identity identification information of the printing consumable to a verification center in a wireless mode to carry out validity verification; receiving validity verification results fed back by the verification center; and forwarding the validity verification results to a printer host so that the printer host determines whether to execute printing work according to the validity verification results. According to the safe printing method, the chip, theprinting consumable and the printer, a mode of remotely verifying the validity of the printing consumable by the verification center is realized, the verification work is finished by the verificationcenter, and the verification center is capable of verifying the validity of the printing consumable by combining a current latest and most authoritative verification technology, so that deciphering of the chip and the verification technology by other people are effectively prevented, and illegal production and imitation of the printing consumable are avoided.
