GENERAL INFORMATION

The Resolution Enhancement Technology (RET) introduced with the HP
LaserJet III represents a technical milestone in the history of desktop
laser printers. RET eliminates the fine stair steps normally seen on
diagonal lines from printers with conventional 300 dpi controllers. RET
uses variable dot sizes to smooth jagged lines and edges on all types of
text and graphics. It also sharpens corners and intersections by placing
smaller dots at the pointed tips. The result is print quality that has
the sharpness of 600 dpi on the edges.

The LaserJet III also introduced the PCL 5 printing language with
enhanced page formatting features. PCL 5 is a superset of PCL 4, which
is built into other LaserJets. It provides the LaserJet III with much of
the functionality of PostScript without the cost and processor overhead.
All older PCL 4 applications should print perfectly with PCL 5. HP also
integrated its industry standard HP-GL/2 pen plotter language into PCL
5. HP-GL/2 allows graphics to be described very efficiently and many CAD
applications require it. Older LaserJet II printers required PDP's
Plotter-in-a-Cartridge product to emulate HP-GL/2.

PCL 5 was conceived as a substitute for PostScript much in the same way
Canon developed CaPSL. A major shortcoming of CaPSL is that it's a
dead-end for higher print quality; there are no typesetters that use
CaPSL. Most publishers using PostScript use low-cost 300-dpi laser
output for drafts and then print to PostScript-equipped image setters,
such as a Linotronic machine, for the final film.

This exact correspondence between low cost proof copies and
typeset-quality camera-ready copies has been one of the key ingredients
for the phenomenal success of PostScript and its creator, Adobe Systems,
Inc. HP realized that in order for PCL 5 to be a substitute for
PostScript, there had to be high resolution typesetting equipment
compatible with PCL 5. So HP teamed up with CompuGraphic to use CG's
Intellifont type fonts and scaling technology as part of PCL 5. Together
they wrote a program called DirectSet that translates PCL 5 commands
into code for the AGFA Compugraphic Series 9000 imagesetters.

To hedge its bets, HP also contracted with Adobe to provide a PostScript
cartridge for the LaserJet III. Resolution Enhancement Technology works
well in the PostScript mode, but you should disable RET when printing
scanned images because the dots added by the RET circuitry to smooth the
image tend to reduce clarity. The LaserJet III allows the operator to
turn off RET from the control panel. The LaserJet III sold far better
than expected and was in short supply during all of 1990. The III was
HP's third grand slam in the printer business and is one of the most
popular printers on the market.
