DLE EOT n
[Function] Sending status in real time
[Code] <10>H<04>H<n>
[Range] 1 ≤ n ≤ 4
[Outline] Sends in real time the status specified by "n."
n = 1: Printer status
n = 2: Status caused by an offline condition
n=3: Statuscausedbyanerror
n = 4: Paper detector status
[Caution] • Each status represents the current status. It is 1-byte data.
• The status is transferred without checking whether the host is ready to receive or busy.
• This command is executed even if the printer is in offline state, receive-buffer full state, or
error state.
• This command is dealed with when it is received.
•Ifanotherdatastringof<16>H<04>H<n>(1≤ n ≤ 4) is received, the printer acts the same
way as with this command. Therefore, the user should be reminded of this fact.
[Example 1]
Suppose a command "ESC * m nL nH [d1 ... dk]," where d1 = <10>H, d2 = <04>H, d3 =
<01>H.
• The DLE EOT 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 EOT 3 when the host has sent down to ESC 3 in its attempt to send
ESC 3 n, the printer handles the ESC 3 as ESC 3 <10>H. Thus, the user should be cautious.
• If ASB (automatic status back) is enabled by GS a, it is necessary to discriminate between
the status due to AS and the status due to this command.
