Choosing The Correct Pen And Medium - HP 7475a Operation And Interconnection Manual

describe these procedures and include instructions for choosing the
correct pen and medium combinations.

Choosing the Correct Pen and Medium

To obtain plots of the highest quality, it is important to use pens and
are
media that matched to your application. Two types of liber-tip pens
are
recommended: one for plotter paper and one for transparency film.
The top of each pen is marked, in a color that matches the pen's ink,
with a three-character code. The first character denotes the media on
which the pen is designed to draw. The "P" is for plotter paper; "T" is
for transparency film. The second and third characters specify, in
millimetres, the approximate line width that the pen will draw.
