PROBLEM TO BE SOLVED: To provide a printer, an information processor, a control method therefor and an information recording medium capable of preventing a malfunction of the printer without requiring a complicated detecting operation of the information processor even when binary data having the same data string as that of a real time command having priority in execution. SOLUTION: A receiving/analyzing operation section of a printer receives a data string including one of or a combination of a real time processing command, a normal processing command and a binary data transferring command. When it receives a binary transferring command, an interruption terminal switching circuit 105 switches one interruption terminal INT0 of a CPU to the other interruption terminal INT1. After that, while the data string corresponding to the binary data transferring command is received, the processing corresponding to a real time command is not executed.
