DLE ENQ n
[Function] Real-time request to printer
[Code] <10>H<05>H<n>
[Range] 1
n 2
[Outline] The printer responds in real-time to the request that the host
specifies with number “n”.
[Caution] This command is only effective if an auto cutter error has
occurred.
This command is dealt with when it is received.
This command is also executed even if the printer is in a
receive-buffer full state.
If another data string of <10>H<05>H<n>(1
n 2) is received,
the printer acts in the same way as with this command. The
user should, therefore, be reminded of this fact.
[Example 1]
If, for example, a command “ESC * m nL nH {d} k”, where d1 =
<10>H, d2=<05>H, d3=<01>H1, is given, the DLE ENQ n
command cannot be interleaved into the code string of another
command consisting of two bytes or more.
[Example 2]
• If the printer sends DLE ENQ 2 when the host has sent up to
ESC 3 in its attempt to send ESC 3 n, the printer treats the ESC
3 as ESC 3 <10>H. Thus, the user should be careful.
Even if DLE ENQ 2 is executed, the settings made by, for
example, ESC ! and ESC 3 retain the conditions when the error
occurred. A combined use of this command and ESC @ can
completely initialize the printer.
