DLE ENQ n
[Name] Real-time request to printer
[Format] ASCII DLE ENQ n
Hex 10 05 n
Decimal 16 5 n
[Range] 1 ≤ n ≤ 2
[Description] Responds to a request f rom the host computer. n specifies the requests as follows:
n Request
1 Recover from an error and restart printing from the line where the error occurred
2 Recover from an error aft clearing the receive and print buffers
[Details] • W hen the printer is disabled with ESC = (Select peripheral device), this command is effective.
• This com mand is effective only when an autocutter error occurs.
• The printer st arts processing data upon receiving this command.
• This com mand is executed even when the printer is offline, the receive buffer is full, or there
is an error status with a serial interface model.
• W ith a parallel interface model, this command can not be executed when the printer is busy.
This command is executed even when the printer is offline or there is an error status when
DIP switch 2-1 is on with a parallel interface model.
• 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 (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 print head temperature error.
[Notes] • 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 com mand 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.
