The illustration below shows how you can use a grid to plan
where you want dots to be printed. This grid is for a sin le line of graphics 42 columns long. Since each line of
approximately 1/8th of an inch high and since
The actual pattern that the LQ prints on the paper is, of course, made up of dots that overlap each other both vertically and horizontally. The reason the planning grid uses an x for each dot is that using an accurate representation of the dots makes calculating the data numbers difficult because they cover up each other.
Therefore, remember that each x represents the center of a dot, and the dots actually overlap each other.
Write the assigned values of the pins next to your design and then total the values for each column of dots. These totals are the values that will be sent to the printer as graphics data to print the design.
