A recording device is connectable to a host computer and performs recording on the basis of received data including commands, received from the host computer. A receiving buffer stores therein the received data received from the host computer. A command detection section reads the received data stored in the receiving buffer while scanning the receiving buffer with a first read pointer to detect the commands included in the received data. A command execution section processes the commands detected by the command detection section in a stored order of the commands in the receiving buffer. An immediate processing command detection section reads the received data stored in the receiving buffer while scanning the receiving buffer with a second read pointer which is provided separately from the first read pointer to detect an immediate processing command included in the received data. The command execution section preferentially processes the immediate processing command detected by the immediate processing command detection section regardless of the stored order of the commands in the receiving buffer.
