Pen plotters print by shifting a pen or other device across
the face of a piece of paper. This signifies that plotters are vector graphics
apparatus, rather than raster graphics as with other printers. Pen plotters can
illustrate multifaceted line art, including text, but do so unhurriedly because
of the power-driven movement of the pens. They are time and again incapable of
capably creating a solid area of color, but can hatch vicinity by sketching a
number of close, standard lines.
Plotters presented the fastest way to economically create
very large drawings or color high-resolution vector-based artwork when computer
memory was very high-priced and processor power was much regulated, and other
kind of printers had restricted graphic output capabilities.
Pen plotters have in essence become outdated, and have been
supplanted by large-format inkjet printers and LED toner based printers. Such
devices may still comprehend vector languages initially designed for plotter
use, since in many uses; they recommend a more economical alternative to raster
data.
Hewlett-Packard made its first acquirement in 1958 when it
acquired the F Mosley company from California. Mosley made graphics recorders
for implements. This industry subsequently became the San Diego Department
which made Hewlett-Packard’s pen plotters. In the 70’s, pen plotters were the
only way to get high-resolution hardcopy graphics production from computers.
The outcome of output from graphics printers normally varied between 70 dots
per inch and 100 dots per inch. But, even Hewlett-Packard’s first digital pen
plotters could create a line resolution equivalent to 1000 dpi. Until 1987, pen
plotters were also the lone cost-effective means of getting color output from
computers.
Put side by side to modern color inkjet and laser printers,
pen plotters were very time-consuming and unwieldy to use. Users had to
frequently worry about a pen running out of ink. If one pen ran dried out at
the end of a plot, the total plot had to be re-done. Hewlett-Packard plotters
were also restricted to a maximum of 8 dissimilar colors, without having to
alter pens in the halfway point of a plot. Lastly, plotters could only
illustrate lines and vectors; they couldn't duplicate raster or accurate
images. In spite of these limitations, the extreme resolution and color
capability of pen plotters made them the color hardcopy output device of choice
until the late 80’s. During this time, Hewlett-Packard benefit from a worldwide
market share of over 50%.
Plotters were a fine, while not spectacular, dealings for
Hewlett-Packard through the end of the 70’s. After that, the business expanded
quickly due to 3 factors. 1st, Hewlett-Packard introduced paper-moving plotters
to change the old flatbed technology. 2nd, Hewlett-Packard entered the outsized
-format plotter business which had beforehand been the domain of companies like
Calcomp and Versatec. 3rd, association of Hewlett-Packard pen plotters to non-
Hewlett-Packard systems developed dramatically. The link to non-
Hewlett-Packard systems was driven by use of business graphics on IBM and
well-matched Personal Computers.
These commodities were utilized at Hewlett-Packard’s San Diego Branch. Pen plotters were product line 30 for the section until the product lines were split up in 1989.
