Font Loading
The printer can store 8 fonts in its flash PROM. The memory available for fonts is printed on
the self-test printout. The character size is fixed, so you must load one font file for each
character size you require. The fonts are given font numbers when they are loaded into the
printer. The first font is assigned number 0 and the next font 1 etc. up to font 7. Parameter p14
“Font Selection” will determine what font to use when no font selection command has been
received (see Font Selection

You cannot erase a single font, but must erase font 4-7 with command ESC & D
,
or all eight
fonts with ESC & C, then reload the fonts you wanted to keep.
Windows software for font generation and management is available on the Zebra web site. If
you need to load fonts in a non-Windows environment, use the ESC & NUL command.

The time required for processing the font data that is loaded is typically 15–20 seconds per
font, excluding transfer time. During this time, any data sent to the printer will be lost.

File Format
A font consists of a header describing the font, then data for every character in the font. The
header has to be downloaded even if the font consists of a single character only. Below is a
description of the font header.

description of the font header.
Char_matrix table: 256 records, each containing 3 bytes.
3 byte Char_width (pixels) + Char_Ystart(pixels) + Char_Yheight(pixels)
Char_bitmap data: Bitmap data for all characters that are to be defined.
Note •
The font processing ends with a reset. The presenter motor runs momentarily to
indicate that the printer is ready to be used.
Caution •
Loading to the flash PROM will erase the RAM completely since the RAM is
used during the loading process. Any print data residing in RAM will thus be lost.
