There is disclosed an information processing apparatus, such as a printer, capable of selectively using plural control programs by utilizing an external memory, such as a program cartridge, containing additional programs. When a switching of control program is requested for example by a switch, the start address of the requested program is indirectly obtained by referring to a fixed address of the memory cartridge containing the requested program.

System for switching from a first control program to a second control program based on discriminated transport status of recording medium

System for switching from control program stored in an output apparatus

Information processing apparatus which discriminates whether or not

An electronic equipment includes a memory for storing information necessary for the execution of control programs and identification information which identify the control programs. A first check determines whether the identification information of the control program to be executed is equal to the identification information stored in the memory. A second check determines whether there is a vacant area in the memory when the decision by the first check indicates non-equality, and a control unit stores the information necessary for the control program to be executed in the memory together with the identification information thereof when the second check detects a vacant area.
