ESC ENQ P n1		Parameter-setting Data Enquiry
1B 05 50 n1	Hex
27 5 80 n1	Decimal

This command requests information about the setting of parameter n1, that is, the parameter value stored in flash PROM or any parameter value temporarily set by other ESC commands.

n= 1	gives the setting of parameter 1, etc. The parameter names are listed
	under Summary of Parameter Settings on page 73.
n = 0	gives a response where the first two bytes specifies the length of data to
	come (high-byte, low byte), and followed by a block of data for all
	parameters in the temporary setup.

ESC ACK n1		Acknowledge Marker
1B 06 n1	hex
27 6 n1	decimal

n =

One-byte marker. Range 1 to 255

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.
