A memory card is a media which the printing data are read from and
written into. The printer can print the data by using the memory
card.
Note:
Although the printer is capable of using memory cards, Intermec does not
support this facility. Neither does Intermec provide any means for programming
memory cards.

Memory card

When the printing operation starts with the memory card installed
in which the printing data are stored, the gate array in the formatter
PCB starts to identify whether the printing data are the image data
or the code data. If the printing data are image data, the data are
transmitted to the bit map RAM inside the formatter PCB, and after
transmission of the data completes, the printing operation will start.
On the other hand, the printing data are the code data, the gate array
develops the image data in the bit map RAM in accordance with the
information of the data ( printing position, direction, character size,
and character code). Character font data are stored in the CG ROM
inside the formatter PCB.
When the development of the image data to the bit map RAM
completes, the printing operation starts.
