Print Flash Logo

ASCII
FS p n m
Hexadecimal 1C 70 n m
Decimal
28 112 n m
Print flash logo ID n using mode m. See command 1D 2F m for description of mode m. See
command 1C 71 for description of n.

Define Flash Logos

ASCII
FS q n [xL xH yL yH d1 ...dk]1...[xL xH yL yH d1 ...dk]n
Hexadecimal 1C 71 n [xL xH yL yH d1 ...dk]1...[xL xH yL yH d1 ...dk]n
Decimal 28 113 n [xL xH yL yH d1 ...dk]1...[xL xH yL yH d1 ...dk]n
Define n flash logos specified by IDs 1 through n. Maximum size of logos is determined by
amount of flash allocated to logos. See command 1D 22 80... for flash allocation.
0 < xH:xL < 1024 max printable xH:xL = 72 = 576 dots wide
0 < yH:yL < 256
For each logo definition: xH:xL times 8 dots in the horizontal direction, yH:yL times 8 dots in the
vertical direction. Total data definition bytes k = xH:xL times yH:yL times 8 bytes. See command
1D 2A x y ... for description of data definition bytes arrangement.
During execution of this command printer turns off USM and Real Time status processing. The
printer goes busy when writing to flash. At the end of this command the printer resets.

Select the current logo

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 defined or printed. The active logo n remains in use until this command is sent
again with a different logo n.
When this command precedes a logo definition, that definition is stored in flash or RAM memory as logo n. If there is
already a different definition in flash memory for logo n, the first is inactivated and the new definition is used. The inactive
definition is not erased from flash and continues to take up space in flash memory.
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.
