Commands related to auxiliary functions
DLE ENQ n
[Designation] Real-time request to printer
[Format] 10H, 05H, n
[Valid limits] 0 n 2
[Initial value] -
[Function] (1) Responds in real-time to requests from the host specified using parameter n.
(2) The table below lists the operations based on the value n:
n Function
0
When switch pressing waiting of GS ^,the same processing as one
switch pressing is executed.
1
Restarts printing from the beginning of the line where the error
occurred after the cause of the error is corrected.
2
Recovers from the error after the receive and print buffers are
cleared.
(3) This command(n=1,2) is valid only when a cover open error.
(4) This command is processed upon being received.
(5) The print start after recovers from an error by command(n=1), it is from the
next line of the error generation.
(6) Processing is executed in offline, receive buffer full, or error states.
(7) The status when an error occurs is retained for the following settings:
a. Select print mode(s) command (ESC !)
b. Set line spacing (ESC 3)
(8) The printer is fully initialized using this command and the Initialize the printer
command (ESC @).
(9) For other commands too, the same operation as this command is performed
when a data sequence of 10H 05H n (1 n 2) is received. The user must be
made a ware of this. For example, d1 = 10H, d2 = 05H, d3 = 01H for ESC * m nL
nH [d]k
(10) This command cannot be placed between or among bytes that form the code
sequence of another command, such as:
a. ESC sequence
b. GS sequence
For example, the data will be processed as ESC 3 10H if an attempt is made to
send ESC 3 n from the host and DLE ENQ 2 is sent after ESC 3 is sent. The
user must be made aware of this.
(11) For DLE ENQ 2, the printer is recovered from the error after the receive and
print buffers are cleared.
