Epson EPL-N1600 Reference Manual page 123

If you select the BarCode setting, 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 been
printed, and may also cause some distortion when printing bit
image graphics.
ZeroChar
Selects whether the printer prints a slashed or unslashed zero.
This is useful for distinguishing between an uppercase O and a
numeric 0 when printing program listings, for example.
