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.

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.
