The BarCode setting 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. BarCode is not available in I239X mode.
This mode reduces the size of the image being printed and may
cause some distortion when printing bit-image graphics.
ZeroChar
This option determines whether the printer prints a slashed
zero (0) or an unslashed zero (0). This feature is useful for
clearly distinguishing between an uppercase letter O and zero
when printing documents such as program lists.
The table below shows the available parameters for each setting
in ESC/P 2 and FX modes. See the previous pages for a
detailed description of each setting.
