  • Publication number: 20240127021
    Abstract: An acquisition portion of a pretreatment control apparatus acquires identification information capable of identifying a treatment medium (step S1). A first transmission portion transmits a pretreatment instruction based on the identification information to a pretreatment device which performs a pretreatment with respect to the treatment medium (step S13). A second transmission portion transmits a transmission instruction for identified print data based on the identification information, to a storage device which stores print data (step S3). As a result, the pretreatment control apparatus can transmit the pretreatment instruction and the identified print data by acquiring a single piece of identification information. Therefore, the number of processing steps by the pretreatment control apparatus is fewer than when the pretreatment instruction and the identified print data are transmitted by acquiring different information.
