Description The [ESC] y <n> command enables and disables command set features.
It is possible that the IPCL commands will interfere with print data. If this occurs, the
IPCL can be disabled with an [ESC] y <4> command.
Note 1: Once IPCL commands are disabled, the Enable IPLC command will
not be a valid IPCL code.
Note 2: [ESC] y <0>, <1>, <2>, and <3> allow the printer to switch between
emulation modes. When the switch takes place, the current print buffer is
printed, and the printer reinitializes. These commands do not permanently
change the configuration. A power on reset restores the mode that was
configured in menu mode. A reset by command or from the INIT pin does not
restore the mode.
Note 3: [ESC] y <6> and <7> enable and disable the inquire process. These
commands are not processed as they are received, but are buffered then
processed. The buffering process allows inquire commands sent after a
disable to be answered. In addition, inquires sent after an enable may not be
answered. (See additional notes 3 and 4 on the next page).
Note 4: In EPOS mode, the [ESC] y command is active.
