TH320/TH420
Programmers Guide
69
When unsolicited status mode (USM) is enabled using the enable/disable unsolicited status mode
command (1D 61), the status transmitted by this command (transmit status) and the USM status must
be differentiated according to the information found in recognizing data from the printer. This is found
in the real time commands section of this document.
The status bytes to be transmitted are described in the following four tables.
Exceptions
When n is out of the specified range, the command is ignored.
Unlike the A756, that had a dedicated connector and resultant dedicated status reporting for each
cash drawer, TH320/420 have 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.
