iDP3221 User’s Manual

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 specified with number "n."
		n = 1: After recovering from an error, the printer resumes printing from the beginning of
		the line where the error occurred.
		n = 2: The printer clears the receive buffer and the print buffer, and then recovers from the
		error.
[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 or error 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>H, 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 down 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.
	• When DEL ENQ 2 is executed, the settings made by, for example, ESC ! and ESC 3 remain
	the same as those in effect when the error occurred. A combined use of this command and
	ESC @ can completely initialize the printer.
