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

In an output method and apparatus for a printing device, a plurality of buffers are provided. The method and apparatus can determine data having the highest priority, and preferentially output the determined priority data.

Output method and apparatus for a recording device

An outputting apparatus having a mode which rotates a character pattern and outputs the rotated pattern. A predetermined pattern is stored in a memory in a rotated state. A rotated pattern is read out of the memory in accordance with a signal designating the output mode when it is stored in the memory, and output as it is.

Outputting apparatus

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.

Electronic equipment including non-volatile memory means for storing

There is provided a printing apparatus having a font pattern memory to store portrait font patterns and a pattern converter to convert the portrait font pattern which is read out of the font pattern memory into the landscape font pattern, in which both of the portrait printing process and the landscape printing process are executed. This printing apparatus comprises: a frequency information memory such as a nonvolatile memory to store print frequency information of each of the portrait font patterns; a managing circuit to update and manage the print frequency information which is stored into the frequency information memory in parallel with the printing process; a landscape memory to store a predetermined number of landscape font patterns converted by the pattern converter on the basis of the print frequency information which is updated and managed by the managing circuit so that the landscape font patterns can be updated; and a landscape font pattern generation controller for comparing input print information with the print frequency information and for preferentially generating the landscape font pattern from the landscape memory. Thus, a desired landscape font pattern can be efficiently generated and printed at a low cost and the landscape printing process according to the latest print frequency information can be always executed.
