Character set commands
Transferring the design onto a dot grid
The document printer prints characters as dot patterns. A character consists of
a maximum of 24 dots in a vertical direction (spacing 1/ 180 inch). In a horizontal
direction, the number of dots and the densitiy depend on the print quality:
– 9 dots (spacing 1/120 inch) in draft print quality
– 29 dots (spacing 1/360 inch) in LQ print quality
– 37 dots (spacing 1/360 inch) with proportional spacing.
To ascertain the dot pattern, the character design is transferred onto a dot grid
appropriate to the desired print quality.
The following diagrams show the dot patterns for the character 'I' on different dot
grids.
