Abstract: A printer includes a receiver, an inserter, and a sort controller. The receiver receives print data. In response to detection of a change in a reception condition for receiving the print data by the receiver, the inserter inserts separator information between a print data portion received before the detection and a print data portion received after the detection, and thereby generates print data including the separator information inserted thereinto. In response to detection of the separator information from the print data including the separator information inserted thereinto that is sequentially input from the inserter, the sort controller performs control to sort a printout of a print data portion after the detected separator information from a printout of a print data portion before the detected separator information.
