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. The select slip command x/C must be disabled via 1F 03 38 00 to use this logo command.

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 throughn. Maximum size of logos is determined by amount of flash allocated to logos. See command 1D 22 80… for flash 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 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 (downloaded bit image)

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 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 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. Continued . . .
