ESC B and other commands

The scanner ignores the image processing you select with the ESC B command if you have already selected 3 bits/color/pixel or higher with the ESC D command.

2. Download dither pattern (ESC b)

This command defines the dither pattern that is selected when you use ESC B to select user-defined dither patterns A and B. You can select square patterns with sizes of 4×4, 8×8, and 16×16. You define the dither pattern by assigning a threshold data value to each pattern member. Since image data has a value from 0 to 256, you can set the threshold value from 0 to 256.

The threshold values you define with this command remain in effect until you turn off the scanner or redefine new values. The ESC @ (Initialize the scanner) command does not clear these values.
