ESC v

[Name]	Sending of the printer status (only Serial interface)
[Code]	<1B>H <76>H
[Function]	Sends the status of the printer at the current point of time.
[Items requiring caution]
	The status that is sent will be 1 byte of data, and the contents will be as shown in the table
	below. When the control is set to DTR/DSR, 1 byte only should be sent after confirming
	that the host is in the receiving possible condition (the DSR signal is at 'space'). Further,
	when the control is set to XON/XOFF, one byte only should be sent without confirming
	the DSR signal condition.
	When the control is set to DTR/DSR and the host is in the receiving not possible
	condition (the DSR signal is at 'mark'), wait until the DSR signal is in the receiving
	possible condition. In the paper end (paper near-end) condition, there may be instances in
	which receiving of this command may not be possible due to the BUSY condition.
	This command will only be effective in serial interface printers .
