Pen Although this printer is a laser printer the HP-GL/2 and HP-GL graphics languages
retains the notion of a pen and allows you to select between two pens, white and
black. You must select a pen before you can draw anything. The HP-GL and HP-
GL/2 language were originally developed for use with plotters and the terminology
remains.
