5-6 Commands
[Reference]
DLE ENQ
, ESC u, ESC v, GS a, GS r
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] The printer responds to a request from the host specified by n. The
operations performed depend on the value of n, as follows:
n = 1: Restarts printing from the beginning of the line where an
error occurred, after recovering from the error.
n = 2: Recovers from an error after clearing the receive and
print buffers.
[Notes] • The command is effective only when an auto-cutter error occurs.
• The printer executes this command upon receiving it.
• This command is also executed when the receive buffer is full.
• The status is transmitted whenever the data sequence of 10H(16)
05H(5)n (1
≤
n
≤
2) is received.
Example:
In ESC
✻
m nL nH [d] K , d1=10H(16) , d2=05H(5) , d3=01H(1)
• This command should not be used within the data sequence of
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
10H(16) for DLE ENQ 2 is processed as the code for ESC 3
10H(16).
