Real Time Request to Printer
The printer responds to a request from the host specified by n. The operations performed
depend on the value of n, according to the following parameters.
GS Sequence
Hexadecimal Decimal ASCII Value of n
1D 03 n 29 3 n GS ETX n
1 = Recover and restart
2 = Recover and clear buffers
The command is ignored if n is out of range.
DLE Sequence
Hexadecimal Decimal ASCII Value of n
10 05 n 16 5 n DLE ENQ n
1 = Recover and restart
2 = Recover and clear buffers
The command is ignored if n is out of range.
Note: An application using the DLE 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 GS ETX n
sequence which is handled exactly the same as DLE ENQ n.
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.
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 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.
