Status Reporting Commands
10/05/2009 TTP 7030™ Technical Manual P1003636-002
The "acknowledge marker" n is placed in the command queue and when the execution of
commands reaches the marker it is sent back to the host computer. This is an addition to the
status commands that pass the queue and are answered immediately when received.
ESC ACK n1
Acknowledge Marker
1B 06 n1 hex
27 6 n1 decimal
n1 One-byte marker. Range 1h to 255h
Example •
"Print data" <LF><ESC>p<ESC><ACK><1>
Wait for <1>
<RS><ESC><ACK><2>
Wait for <2>
The printer will send <1> when <print data> has executed and <2> when the ejecting has
been performed.
Note • You must wait for the acknowledge marker to return before sending any more data to
the printer.
Note • Acknowledge marker cannot be used for events that write to the flash PROM, for
instance font loading. This is because the writing procedure erases the buffer, including the
markers, and uses all RAM in the printer.
