Using Flash Memory Graphics
You can also use a graphic stored in flash memory. You are limited to one
graphic stored in memory at a time. Saving a graphic to flash memory when
there is already one there overwrites the previous one.
1.
Remove the printer’s battery and wait several seconds.
2. Re-insert the battery and enter Download Mode immediately. It takes two
commands to enter Download Mode:
ESC DL
Have the host wait to send the second command until the printer
responds to the first command by returning a ‘?‘ character.
ESC LG0
3. Send the graphic one line at a time using the ESC-V command as described
in “Using Data Stream Graphics.”
ESC V 1 0
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFFFFF
4. Save the graphic to flash memory using the following command:
ESC LG FF hex
When the printer receives the command, it returns a ‘D‘ character, and
begins the save. When the save is complete, the printer sends a ‘!’
character, and then an ‘X’ character every 500 milliseconds.
5. Remove the printer’s battery and wait several seconds before replacing it.
6. Print the flash memory graphic with the following command:
ESC Lg0
