ABSTRACT:
Embodiments of the invention include a toner cartridge for the printing of MICR characters that includes a memory device that is programmed with the requisite font for MICR characters. The font is accessible for the printing of MICR characters when the toner cartridge is installed in a printer. In a further embodiment, the memory device on the toner cartridge may also contain a data flag indicating that a print job must print at least one symbol in the MICR font. Corresponding printer firmware may then determine if this flag is present, and, if present, will prevent the printing of print jobs that do not include at least one character to be printed in the MICR font. This prevents MICR toner from being wasted on documents that do not require MICR toner, such as normal office correspondence.
