Request printer reset
[ENQ] <10>

Reset printer

ACK <10> (06H 0AH)
The command was accepted.
NAK <10> (15H 0AH)
The command was rejected.
The ENQ <10>, EPOS "DLE ENQ n" commands, and the INIT pin all have
the same effect and are termed "Reset" commands. To prevent data loss, the
printer will try to finish printing any buffered data. This will fail if operator
intervention with the printer is required. The reset operation is saved until
the printer goes idle. In the case of the slip request command or any
command that waits for the operator, the printer is idle. If the printer is idle
and a reset is received or pending, the printer will reset, and the buffer will
be cleared. If the host resets an operator intervention operation, any
remaining buffered data will be cleared.
When the printer receives a reset command, the printer will go off-line
and/or show a busy signal until the reset completes. In serial mode, the
printer can have information in its high-speed buffer that was received after
the reset command was issued, but before it was processed. If the host
application continues to send information to the printer after a reset
command, some of that information may be processed before the reset is
processed. In parallel mode, the printer will go busy after the reset is
received and before the next byte is accepted.
The printer will accept an [ENQ] <10> in parallel mode. It will not be
acknowledged, however. If both the serial and parallel ports are active, the
serial reset will not be acknowledged either because the reset operation will
remove the parallel response. In parallel, IEEE 1284 mode, the response
buffer is cleared by a reset command preventing responses in IEEE 1284
mode as well.
There is a menu selection that will block the command. If reset inhibit is set
in the configuration menu, the command will be ignored.
