The [ESC] y <n> command enables and disables command set features.
It is possible that the IPCL commands will interfere with the print data. If this is the
case, they can be disabled with an [ESC] y <4>.
1. Quiet mode operation prints by making two passes for every pass in normal
mode. It generates less noise because only half the print wires are activated in
each pass. Quiet mode is slow and should only be used if quiet operation is
necessary.
2. ESC y <2> and <3> allow the printer to be switched between normal and EPOS
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 will restore the mode that was configured in
menu mode. A reset by command or from the INIT pin will not restore the mode.
3. ESC y <6> and <7> enable and disable the inquire processing. These commands
are not processed as they are received, but are buffered and then processed.
Because of this, [ENQ] commands sent after a disable may be answered. In
addition, [ENQ]'s sent after an enable may not be answered.
4. The printer has a resident OCR-MA font that only works in utility mode and
contains Group 2 characters. They are defined and mapped per ANSI X3.111-
1986. Once mapped into a code page, they can be removed by issuing an [ESC]
y <12> command or a code page select command.
The [ESC] y command is active in EPOS mode; however, Modes 5 and 6 are
disabled.
