Description
➊ By means of this MTPL-sequence the eighth data bit is set to “1”.
This results in accordance with the selected character set characters from the national
character set or italic characters to be printed.
➋ By means of this MTPL-sequence the eighth data bit is set to “0”.
This means that wrong character printing caused by the eighth data bit set high by the
system can be avoided.
CSI 9 z is ignored
– if Extended Character Set is selected,
– if Graphic Mode is selected
Note that following the sequence CSI 8 z all subsequent control sequences must begin
with an “ESC [ ”, because CSI (9B) cannot be represented by a 7 bit code.This remains
in effect until the printer receives either the sequence ESC [ 9 z or ESC [ 7 z .
