2.2.7 Status Commands

DLE EOT n

Support model
[Function] Sending status in real-time
[Code] <10>H<04>H<n>
[Range] 1≤n≤4
[Outline] [The specification which is common to the model]
• Sends in real-time the status specified by "n".
[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 10H 04H 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 = 10H, d2 = 04H, d3 = 01H.
• 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 10H. Thus, the user should be cautious.
