two sequences: GS and DLE. The operations performed depend on the value of n,

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.
If the receipt is selected, this command will attempt recovery from a knife error. Other
errors associated with the receipt, such as paper out or print head overheating, can be
recovered from only by clearing the specific condition, such as loading paper or letting the
print head cool down.
