1
Recover from an error and restart printing from the line where the error occurred
2
Recover from an error at clearing the receive and print buffers
[Notes]  This command is effective only when an auto cutter error, a black mark detecting
error or a platen-open error occurs.
 The printer starts processing data upon receiving this command.
 This command is executed even when the printer is offline, the receive buffer is full,
or there is an error status with a serial interface model.
 With a parallel interface model, this command cannot be executed when the printer
is busy.
 The status is also transmitted whenever the data sequence of <10>H<05>H<n> (1
n 2) is received.
Example:
In ESC m nL nH dk, d1 = <10>H, d2 = <05>H, d3 = <01>H
 This command should not be contained within another command that consists of
two or more bytes.
Example:
If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the host
computer) goes to MARK before n is transmitted, and DLE ENQ 2 interrupts before
n is received, the code <10>H for DLE ENQ 2 is processed as the code for ESC 3
<10>H.
 DLE ENQ 2 enables the printer to recover from an error after clearing the data in
the receive buffer and the print buffer. The printer retains the settings (byESC !,
ESC 3, etc.) that were in effect when the error occurred. The printer can be
initialized completely by using this command and ESC @. This command is
enabled only for errors that have the possibility of recovery, except for print head
temperature error.
