 Scanning ...
	DC:0D:30:8F:3A:B8	PTP-II
	D4:9D:C0:43:68:C5	[TV] Samsung 7 Series (55)

Set up RFCOMM communication (RS-232 serial port emulation):

sudo rfcomm connect /dev/rfcomm0 DC:0D:30:8F:3A:B8
Connected /dev/rfcomm0 to DC:0D:30:8F:3A:B8 on channel 1
Press CTRL-C for hangup

In QE set in Receipts -> Printer:
