• Each status represents the current status. It is 1 byte data.

 

 

 

[Range]

[Code] 

<

10>H<04>H<n> 

Sending status in real-time

 

• 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. 

• This command can be executed even if printer setting by ESC = is invalid.

 

• 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

 

• With parallel interface specifications, this command cannot be executed while the printer is in Busy 

state. 

• With serial interface specifications, this command is executed in offline state, receiving buffer full 

state, and error state.

 

• This command is dealt with when it is received.

 

• This command is executed even if the printer is in offline state, receive-buffer full state, or error 

state.

 

• The status is transferred without checking whether the host is ready to receive or busy.

 

Sends in real-time the status specified by “n”. 

• The DLE EOT n command cannot be interleaved into the code string of another command 

consisting of 2 bytes or more. 

 

1 Printer 

status 

2 

Status caused by an offline condition 

3 

Status caused by an error 

4 

Continuous paper detector status 

When memory SW1-3 is ON, the printer does not enter Busy state in the offline state and error 
state.

 

Suppose a command “ESC * m nL nH [d1 ... dk]”, where d1 = <10>H, d2 = <04>H, d3 = <01>H. 

[Example 1] 

 

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.
