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.

Abstract: A non-transitory computer-readable medium stores computer-readable instructions. The computer-readable instructions are executed by a processor of a pretreatment information generation device that generates pretreatment information to be used in pretreatment on a recording medium by a pretreatment device. The computer-readable instructions that, when executed by the processor, perform processes including receiving image data to be printed on the recording medium, and identifying the pretreatment information to perform the pretreatment with respect to the received image data.
