To add a new pen, you must redefine pens 0 through 7 first, then add the new pens that you want.

To set pen widths and colors to values other than those in HPGLPENS.PS, do the following steps:

1.If necessary, configure the printer port to receive PostScript; see page C-5 for instructions.

2.Open the HPGLPENS.PS file in a text editor.

3.Edit the file and substitute the values that you want for those in the file. Color values can be any decimal number between 0.0 and 1.0.

For example, to change pen 4 to a purple color and a width of

.5 mm, edit HPGLPENS.PS and change the line for pen number 4 to the following:

4 0.5 1.0 0.0 0.5
