Abstract This invention relates to a printer, an information processing apparatus, control methods for the printer and the information processing apparatus, and a storage medium. The printer is connected to the information processing apparatus to receive a predetermined command and a data stream composed of data or the like for carrying out printing and predetermined processing corresponding to the command. In the printer, a receiver receives a data stream including a normal command and/or a real-time command. When the data stream received by the receiver is a real-time command data stream and when an indication device, provided to give an indication as to whether or not the real-time command is to be executed, indicates permission for the real-time command, a real-time processing section executes real-time processing corresponding to the real-time command data stream. Otherwise, a normal processing section executes normal processing corresponding to the normal command data stream without carrying out the real-time processing.
