Select active user-dened character set
Selects user-dened character set number for download or printing. The default at power on is 0.
ASCII US i n
Hexadecimal 1F 69 n
Decimal 31 105 n
n = 0 - 127
Set high order bit of n to congure user-dened character set number as the default. To congure the printer to print from
the user-dened character set at power, send 1F 3 0F 01 and reset the printer. Information will print on the rst diagnostic
page.
Graphics
These commands are used to enter and print graphics data and are described in order of their hexadecimal codes, unless
otherwise noted.
These commands describe operation for 80mm paper. If the printer supports 82.5mm paper, the dot spacing is the same but
there are 640 printable dots rather than 576 printable dots on 80 mm paper.
Download BMP logo
ASCII: ESC (+*.BMP le)
Hexadecimal: 1B (+*.BMP le)
Decimal: 27 66 77(+*.BMP le)
Value: Maximum width = 576 (640 for 82.5mm paper)
Maximum height = 512
Enters a downloaded BMP logo into RAM or ash.
The downloaded BMP logo can be printed by using the print downloaded bit image (1D 2F m) command.
To downloaded BMP le to save it as a logo, send the hexadecimal code 1B followed by the whole BMP le.
The printer decodes the BMP le 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 denable 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 ash memory had lled up with inactive logo 0 denitions upon next
power cycle). Warnings about the effect of running out of dened 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 100ms to allow the printer time to write the logo to ash.
Exceptions
BMP le images that are not monochrome are put into the print buffer.

This command is recognized in A799 native mode and in A794 emulation.
In A793 and LEGACY emulations, the BMP le bytes are put into the print buffer.
