A.1.0 Flash Based Font Commands
The Unitech Instruments MP200 printer features 128KB of flash memory reserved
for fonts. This allows the MP200 to be flexible enough to fit many specific application
character sets. To protect the fonts from accidental corruption these features are
currently only possible through an RS-232C serial connection and must be the first
commands received by the printer when it is powered on. Following the instructions
below and using the commands from table A.0 you will be able to download fonts to
the printer.

command must be the first <ESC> command received upon activating the

SRAM.
3) When the copying process is complete the CTS will become active and the
printer will transmit a ‘?’ (0x3F)
4) Invalid Characters will be echoed back to the Terminal Device.
5) Load Flash Font Character Using the command from the table A.0.
6) When you are finished Send Quit Command, which will make the printer, copy
the data from the SRAM to the FLASH. When it is done it will send D!X .

location.
