2.2.6 Status Commands

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	Status

1Printer status

2Status caused by an offline condition

3Status caused by an error

4Continuous 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 dealt with when it is received.
	• With serial interface specifications, this command is executed in offline state,
		receiving buffer full state, and error state.
	•	With parallel interface specifications, this command cannot be executed while the
		printer is in Busy state.
		When memory SW1-3 is ON, the printer does not enter Busy state in the offline
		state and error state.
	•	If ASB (Automatic Status Back) is enabled by GS a, it is necessary to discriminate
		between the status due to ASB and the status due to this command.
	•	This command can be executed even if printer setting by ESC = is invalid.
	•	If another data string of <10>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 2 bytes or more.

[Example 2]

If the printer sends DLE EOT 3 after the host has sent up 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.
