Value of
n
:
1 = recover and restart
2 = recover and clear buffers
The printer responds to a request from the host specified by n. This command includes two
sequences: GS and DLE. This command can be disabled using 1F 7A. If in page mode, the printer is
set back to standard mode, causing values set by 1B 57 to be changed back to default. The
operations performed depend on the value of n, according to the following parameters.
n
= 1
Restarts printing from the beginning of the line where an error occurred, after recovering from the
error. Print settings that are normally preserved from line to line, such as character height and
width, are still preserved with this command. This sequence is ignored except when the printer is
busy due to an error condition.
This command will attempt recovery from a knife error. Other errors associated with the receipt,
such as paper out or printhead overheating, can be recovered from only by clearing the specific
condition, such as loading paper or letting the printhead cool down.
n
= 2
Recovers from an error after clearing the receive and print buffers. Print settings that are normally
preserved from line to line, such as character height and width, are still preserved with this
command. This sequence is ignored except when the printer is busy due to an error condition.
The same error recovery possibilities exist as for
n
= 1.
Exceptions
The command is ignored if
n
is out of range.
An application using DLE (0x10) sequence must send ENQ within 100 milliseconds of DLE or the
printer will misinterpret the DLE and execute a clear printer command. Avoid this possibility by
using the ID 03
n
sequence, that is handled exactly the same as 10 05
n
.
