The table below summarizes the font downloading commands supported by the
Escape Sequence: | ESC | F | B | CR |
Hexadecimal: | 1B | 46 | 42 | 0D |
Decimal: | 27 | 70 | 66 | 13 |
Important Font Downloading Notes:
The file to be downloaded must be .BDF formatted.
When downloading, ensure that the metrics of the fonts to be downloaded are equal or smaller than the metrics of the existing font in the location in question; otherwise the fonts will not be downloaded correctly.
The escape sequence ESC D F CR must be the first command after power up, otherwise the printer will print the command instead of executing it. You can also use the commands ESC X X CR command to initialize the printer after other escape commands have been used.
Once a font has been downloaded, press the FEED button twice to exit the downloading mode. Shut the printer OFF by pressing the ON/OFF switch.
Each character’s header uses .DBF font and represents the true size of the font bitmap.
Example1: For a 16x23 font, the header at the beginning of each character must appear as follows: BBX 16 23 0 0
Example 2: For a 10 x 23 font, the header at the beginning of each character must appear as: BBX 10 23 0 0
If the font to be downloaded is one byte in size (8 x 23), the .BDF file must be one byte only in size. Otherwise the firmware will not accept the font!
