Auto CR
Specifies whether the printer performs a 
carriage-return/line-feed (CR-LF) operation whenever the 
printing position goes beyond the right margin. If you select Off, 
the printer does not print any characters beyond the right margin 
and does not perform any line wrapping until it receives a 
carriage-return character. This function is handled automatically 
by most applications.
Auto LF
If you select Off, the printer does not send an automatic line-feed 
(LF) command with each carriage-return (CR). If On is selected, a 
line-feed command is sent with each carriage-return. Select On if 
your text lines overlap.
Bit Image
The printer is able to emulate the graphics densities set with the 
printer commands. If you select Dark, the bit image density is 
high, and if you select Light, the bit image density is low.
If you select BarCode, the printer converts bit images to bar codes 
by automatically filling in any vertical gaps between dots. This 
produces unbroken vertical lines that can be read by a bar code 
reader. This mode will reduce the size of the image being printed, 
and may also cause some distortion when printing bit image 
graphics.
ZeroChar
Selects whether the printer prints a slashed or unslashed zero.
