Determining the setting values for printing

of the printer, use the following formulas to determine the final
scanning settings.

The parameter values for the ESC R, ESC H, and ESC A commands
then become as follows:

Note:
On scanners that can respond to printers and other various output
devices, you can set the R
PX
and R
PY
values to match the horizontal
and vertical resolution of your target printer.
