5. Flow of printing data
5.1 Data flow
Printing data (electric signal) output from printer controller becomes the printed image following
the flow shown below.
Reference Forming 2 dimensional printed image
When the image is scanned by turning ON/OFF the laser beam according to electric signal
output from printer controller (VIDEO signal: expresses image data by rise or fall of
voltage), a dot image for a line is formed.
When the above mentioned scanning is carried out for 1 screen of an image, a single color
image (2 dimensional dot image) is formed. To obtain a full color image, a 2 dimensional
dot image must be formed for each of the 4 colors.
Resolution is determined by the following points.
Main scanning direction: Number of dots/inch
Sub scanning direction: Number of scanning lines/inch
