Determining the setting values for printing
Based on the size of the image you plan to print and on the resolution
of the printer, use the following formulas to determine the final
scanning settings.
Main scan zoom (%): H
X
=
X × 100

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.
