ABSTRACT:
A font cartridge has a memory which stores font information for a number of different fonts. The number of different fonts or the total memory size may exceed the maximum memory size or number of fonts which may be accessed by a printer at any one time. A switching function, a switch configuration logic, and a controller, allow a user to access different combinations of font data to the printer such that the total number of font data and memory size available to the printer does not exceed its limit at any one time.
