Print ash logo ID n using mode m. See command 1D 2F m for description of mode m. See
command 1C 71 for description of n. The select slip command x/C must be disabled via
1F 03 38 00 to use this logo command.

Dene n ash logos specied by IDs 1 through n. Maximum size of logos is determined by
amount of ash allocated to logos. See command 1D 22 80… for ash allocation.The select slip
command x/C must be disabled via 1F 03 38 00 to use this logo command.
0 < xH:xL < 1024 max printable xH:xL = 72 = 576 dots wide
0 < yH:yL < 256
For each logo denition: xH:xL times 8 dots in the horizontal direction, yH:yL times 8 dots
in the vertical direction. Total data denition bytes k = xH:xL times yH:yL times 8 bytes. See
command 1D 2A x y … for description of data denition bytes arrangement.
During execution of this command printer turns o USM and Real Time status processing. The
printer goes busy when writing to ash. At the end of this command the printer resets.

ASCII GS # n
Hexadecimal 1D 23 n
Decimal 29 35 n
Range of n: 0 – 255
Default: 0
Selects a color or monochrome logo to be dened or printed. The active logo n remains in use until this command is
sent again with a dierent logo n.
When this command precedes a logo denition, that denition is stored in ash memory as logo n. If there is already
a dierent denition in ash memory for logo n, the rst is inactivated and the new denition is used. The inactive
denition is not erased from ash and continues to take up space in ash memory.
When this command precedes a logo print command and n is dierent from the previously active logo selected, the
printer retrieves the logo denition for n from ash memory and prints it. If there is no denition 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 identier. It automatically
stores any new logo denition in ash memory as logo 0, inactivating any previous logo 0 denition. If the ash
memory space available for logos lls up with inactive logo 0 denitions, the rmware erases the old denitions at the
next power cycle. This is the only case in which the printer erases ash memory without an application command.
