Vertical Clusters Vertical clusters are groups of two or three narrow characters side-by-side in a vertical line of text. Vertical clusters containing half-width characters can be created by using a combination of print direction and cursor positioning commands. An example of vertical clusters is shown below. The C program that follows was used to generate the PCL commands for this example. In this example, two half- width characters (e.g. 2-digit numbers) were printed as vertical clusters.
