FONT DOWNLOAD MODE
A Flash ROM is used to internally store and delete font data and custom designed character
data. The storage capacity for custom designed characters is a maximum of 95 for each type of
16 x 16, 22 x 22, and 24 x 24 dots.
There are four transmission protocols for font download: (1) Download Font Storage, (2)
Download Font Deletion, (3) Download Font Information Aquisition, (4) Storage Custom-
Designed Character. The return status from the printer is set between STX (02H) and ETX (03H),
and transferred in 3 bytes. Note that the return status for the font data transfer when storing font
is 1 byte of ACK (06H). All status data transferred from the host are set between STX (02H) and
ETX (03H), and transferred in 3 bytes.
Wiring on the computer side may require a CTS (pin 5) and RTS (pin 4) cable connection.
Confirm the host settings before downloading.
Figure 5-11 provides the specific sequence of events required by the operator, the printer, and
the printer’s software for font download mode to be activated.
