Enters one line of 7 (slip in 7156 mode) or 8-dot double-density graphics into the print
buffer. Any print command is required to print the line, after which the printer returns to
normal processing mode. The number of bytes sent is represented by the formulas in the
table.
Each bit corresponds to one horizontal dot. Compare to Set Bit Image Mode (1B 2A, m=1)
earlier in this document.
Exception:
1B 4C n1 n2 d1 ... dn is only valid in 7156 Emulation Mode.
Select the Current Logo (Downloaded Bit Image)
Hexadecimal:
Selects a 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
