Print Quality
The dot-matrix impact printhead forms a character by printing dots
in a rectangular arrangement of dot cells called a dot matrix.
The following figure shows some examples of dot-matrix characters.
Each character is printed in a 7-dot by 9-dot matrix. Three columns
of blank dots at the right side of each character, the intercharacter
space, provide the proper horizontal spacing between characters.
