DLE ENQ n

[Name] Real-time request to printer
[Format] ASCII
Hex
Decimal
1 £ n £ 3
[Range]
[Description] Responds to a request from the host computer. n specifies the request as follows:
n
1 Recover from an error and restart printing from the line where the error occurred
2 Recover from an error after clearing the receive and print buffers
3 Cancel the slip waiting status
· The printer starts processing data upon receiving this command.
[Notes]
· This command is also executed when the printer is off-line, when the receive buffer is
full, or when an error occurs.
· The status is also transmitted whenever the data sequence of 10H (16), 05H (5),
n (1 £ n £ 3) is received.
· This command should not be contained within another command that consists of 2 or
more bytes.
· DLE ENQ 1 starts printing from the line where an error occurred. This command is
enabled only for errors that have the possibility of recovery, except for a print head
temperature error.
· When the printer recovers from an error using DLE ENQ 1 and slip paper is selected,
the printer ejects the slip completely and loads paper. However, the printer only ejects
the slip and does not load paper when it recovers from a slip ejection error.
· DLE ENQ 2 enables the printer to recover from an error after clearing the data in the
receive and the print buffers. The printer retains the settings (by ESC !, 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 a print head temperature error.

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, then DLE ENQ 2 interrupts
before n is received, the code 10H (16) for DLE ENQ 2 is processed as the code for
ESC 3 10H (16).
