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 .
Real time printer status transmission

1D 05
29 5
Transmits one byte status of the printer in real time.
Value of byte:
Bit Off/On Hex Decimal Function
0 Off 00 0 Paper adequate.
On 01 1 Paper low (if paper low sensor enabled).
1 Off 00 0 Paper adequate.
On 02 2 Paper low (if paper low sensor enabled).
2 Off 00 0 Cover closed.
On 04 4 Cover open.
3 Off 00 0 Not busy at the RS-232C interface.
On 08 8 Printer is busy at the RS-232C interface.
4 Off 00 0 One or both cash drawers open.
On 10 16 Both cash drawers closed.
5 Off 00 0 Fixed to off.
6 Off 00 0 No error condition.
On 40 64 Error condition exists in the printer.
7 On 80 128 Fixed to on.
* Errors include cover open, paper out, black mark error, cutter error, thermistor error, high or low
voltage error, where a thermistor error is unrecoverable, and a high or low voltage error
automatically recover.
Exceptions
Unlike the A793, that had a dedicated connector and resultant dedicated status reporting for each
cash drawer, the TH210 has a single connector that shares data reporting from either cash drawer.
When either cash drawer is open, an open status is reported by the printer.
