[Function] Real-time request to printer
[Code]
<10>H<05>H<n>
[Range] 0≤ n≤ 2
[Outline] [The specification which is common to the model]
• The printer responds in real-time to the request that the host specifies with number “n”.
n Function
0 At the setting of execution of GS ^ by the FEED switch, the same processing as that pressing the
FEED switch once is carried out.
1 After recovering from an error, the printer resumes printing from the beginning of the line where the
error occurred.
2 The printer clears the receive buffer and the print buffer, and then recovers from the error.
[Caution] [The specification which is common to the model]
• (n = 1) or (n = 2) shall be used after removing the error.
• If another data string of <10>H<05>H<n> (1 ≤ n ≤ 2) 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 = <05>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 ENQ n 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.
• This command is ignored during transmission of block data.
