This command will move the paper on
the receipt in n/203 inch steps instead
of n/152 inch steps.
The dot rows will be measured in n/203
inches versus n/152 inches.
This command sets the right side
spacing to "n" horizontal motion units.
By default, these units are in terms of
1/203 inches versus 1/152 inches.
For graphics commands, the position is
scaled to best match the previous
product. In text mode, the equivalent
character position is calculated.
Since the dots on the new printhead are
smaller, user-defined characters that
were used on the previous printer will
appear smaller on the new printer.
In A756 Emulation Mode, graphics are
scaled to best match the size of the
graphic in the previous printer.
This command uses n in terms of n/360
inches. Since the previous product had
a fundamental step of 1/180 inch and
the new product has a fundamental
step of 1/203 inch, the actual line
spacing will not exactly match the
requested spacing.
