Set zoom and other commands.
The combination of this command and the ESC R (Set resolution)
command determine the maximum number of dots you can scan. You
can calculate the number of dots by multiplying the zoom percent by
the original dot setting.
5. Set scanning area (ESC A)
This command selects the area to be scanned.
The main scan and sub scan are set in units of dots (in the current
resolution) measured from the origin. First you set the ‘‘skip distance’’
from the origin to the beginning of the main scan and sub scan. Then
you set the length of the main and sub scan as measured from the
point defined by the skip distance.
You must always set the main scan length in 8-dot units. However, the
skip distances and the sub scan length can be set in 1-dot units.
ESC A and other commands
Setting the resolution and zoom value determines the maximum
scannable area. You cannot set values that would exceed this
maximum scannable area.
6. Set data order (ESC K)
This command selects the order in which image data is scanned. You
can set the direction from left to right or from right to left.
