When this command precedes a logo print command and n is different from the previously active
logo selected, the printer retrieves the logo definition for n from flash or RAM memory and prints
it. If there is no definition for logo
n
, then no logo is printed.
In the case of a previously existing application that expects only one possible logo, the printer will
not receive the select current logo (1D 23
n
) command. In this case, the printer assigns 0 as the
active logo identifier. It automatically stores any new logo definition in flash memory as logo 0,
inactivating any previous logo 0 definition. If the flash memory space available for logos fills up
with inactive logo 0 definitions, the firmware erases the old definitions at the next power cycle.
This is the only case in which the printer erases flash memory without an application command.
In the case of a new application using multiple logos, the select current logo (1D 23
n
) command is
used. After that, the printer no longer automatically erases the logo definition flash memory page
when it fills with multiple definitions. A new application using multiple logos, writing a user-
defined character set into flash memory, or both, is responsible for erasing the logo and user-
defined character set flash memory page when the logo area is full or before a new character set is
defined.

1–72 (8 x n1 = number of
horizontal dot columns)
1 64 (number of vertical
bytes)
Bytes of data (printed down,
then across) bit gets printed to
1 and not printed to 0
1The number of bytes sent is represented by the following formula:
n = 8 x n1 x n2 (n1 x n2 must be less than or equal to 4608).
Enters a downloaded bit image (such as a logo) into RAM or flash with the number of dots
specified by n1 and n2. If in RAM, the downloaded bit image is available until power is turned off
or reset, another bit image is defined, or initialize printer (1B 40) command is received. This bit
image will be saved as a monochrome logo indexed by current value that was last set by the select
current logo command or 0 is a select current logo command had not yet been given.
The dowloaded bit image can be printed using the 1D 2F command.
See the illustration below for a graphic representation of the downloaded bit image.
