	Serial/Parallel, IEEE 1284	Parallel, non-IEEE 1284
Response	ACK <6> (06H 06H)	PE low
	The position sensor is clear.
	(No form present.)
	NAK <6> (15H 06H)	PE high
	The form position sensor is
	blocked. (There is a form.)

Function	Inquire form clamp status
ASCII	[ENQ] <7>
Hexadecimal	05H 07H
Decimal	<5> <7>

Function	Inquire whether the form clamp is closed
	Serial/Parallel, IEEE 1284	Parallel, non-IEEE 1284
Response	ACK <7> (06H 07H)	PE low
	The clamp is closed.
	NAK <7> (15H 07H)	PE high
	The clamp is not closed.
	(It is open or in jam position.)

Function	Is the buffer empty? Clear IEEE 1284 buffer.

Hexadecimal	05H 09H
Decimal	<5> <9>

Function	This command allows the host to know when the print buffer is
	empty. If IEEE 1284 is active, this command also clears the
	response buffer.
	Serial/Parallel, IEEE 1284	Parallel, non-IEEE 1284
