[Function] Real-time request to printer

After recovering from an error, the printer resumes printing from the beginning of the line
where the error occurred.
1
2 The printer clears the receive buffer and the print buffer, and then recovers from the error.
[Caution] • (n = 1) or (n = 2) shall be used after removing the error.
• If another data string of <10>H<04>H (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.
• This command is ignored during transmission of block data.
