STEP 2 – Enter ash font program mode:
Send <ESC> <‘D’> <‘A’> <0> to select ASCII ash font upload and wait for the printer
to deactivate the CTS line. For the 2500/1500 or the 3750 printers the last number can
be anything between 0..7
STEP 3 – Wait for the printer ready indicators:
Wait for the printer to reactivated the CTS line and transmitted the character ‘?’
STEP 4 – Load new the character:
Upload the user dened ASCII ‘A’ character.
The basic command format and an actual command string are shown below:
<ESC> <‘D’> <ASCII TABLE 0> <Character Code> <46 byte dot matrix data> //for
the 2500/1500 or 3750 the table # does not matter as long as you specied the bank
number.
<ESC> <‘D’> <0> <0x41>
<0x00> <0x00> <0x00> <0x40> <0x00> <0xE0> <0x00> <0xA0>
<0x01> <0xB0> <0x01> <0x10> <0x01> <0x10> <0x01> <0x10>
<0x01> <0x10> <0x03> <0x18> <0x03> <0x18> <0x03> <0xF8>
<0x03> <0xF8> <0x02> <0x08> <0x02> <0x08> <0x06> <0x0C>
<0x06> <0x0C> <0x04> <0x04> <0x04> <0x04> <0x04> <0x04>
<0x0E> <0x0E> <0x0E> <0x0E> <0x00> <0x00>
STEP 5 – Save the modied character to ash:
Sending the command <ESC>-‘D’- <0xFF> {CHR$(27) + ‘D’ + CHR$(255)}, copies
the revised character to the printer ash location.
The printer will transmit the character ‘D’ and then proceed to save the fonts to ash
memory. THE PRINTER POWER MUST REMAIN ACTIVE AT THIS TIME.
STEP 6 – Cycle the printer power:
Once the fonts have been saved into ash memory, the printer will transmit the
character ‘!’.
At this time, the printer will transmit an ‘X’ every 500 milliseconds.
To ensure optimal operation of the printer, remove the battery cartridge from the
printer for several seconds. Replace the battery cartridge and the new fonts will be
ready for use.
