0 = 50
1 = 300
2 = 600
3 = 1200
4 = 2400
5 = 4800
6 = 9600
7 = 19200
b = number of data bits
0 = 7
1 = 8
c = parity
0 = none
1 = odd
2 = even
d = number of stop bits
0 = 1
1 = 2
4.39 PRINTER – REQUEST CONFIGURATION
This command allows the user to request the current printer set-up. It is applicable to both the

• The user enters $I (HEX 24/HEX 49).
• The unit responds with: 09600 8/7 N/O/E 1/2<CR><LF>.
(Baud Rate) (8 or 7 data bits) (none, odd, or even parity) (1 or 2 stop bits)
(carriage return) (line feed).
