ESC (+*.BMP file)
Function:
Download BMP logo
Code ASCII: ESC (+*.BMP file)
Code HEX: 0x1B (+*.BMP file)
Range:
Maximum width = 576
Maximum height = 512
Description: Enters a downloaded BMP logo into RAM or flash.
The downloaded BMP logo can be printed by using the print downloaded
bit image (1D 2F m) command.
To downloaded BMP file to save it as a logo, send the hexadecimal code 1B
followed by the whole BMP file.
The printer decodes the BMP file header and will save the image data after
checking important parameters, such as:
- Width,
- Height,
- Number of colors (only monochrome images are accepted)
BMPs and bit images continue to be definable only for the receipt station.
However, there is no longer an automatic erasure whenever the user
downloads a character set (as happened previously) as well as in the case
where the current logo was never set > 0, (the automatic erasure if user
flash memory had filled up with inactive logo 0 definitions upon next power
cycle). Warnings about the effect of running out of defined logo space
during a download apply (i.e. the command is ignored). The application is
required to manage user data space, downloaded font space, and logo
space.
After downloading a logo to the printer, wait 100 ms to allow the printer
time to write the logo to flash.
Notes:
• Images widther than the maximum width will be cutted on the right side
• Images higher than the maximum width will be ignored.
• Exceptions: BMP file images that are not monochrome are put into the
print buffer.
