HP LaserJet® III printer review
The Resolution Enhancement Technology introduced with HP LaserJet III, represents a technical milestone in the history of desktop laser printers. The RET eliminates the fine stair steps normally seen on diagonal lines from printers with conventional 300 dpi controllers. It 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 small dots at the pointed tips.
LaserJet III introduced the PCL 5 printing language with enhanced page formatting features. PCL 5 is a superset of PCL 4, which is built into other LaserJet’s. It also provides the LaserJet III with much of the functionality of PostScript without the cost and processor overhead. The older PCL 4 applications shall print perfectly with PCL 5. The HP also integrated its industry standard HP-GL/2 pen plotter language into PCL 5. The HP-GL/2 allows graphics to be described very efficiently and many CAD applications require it.
The printer 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 is a dead-end for higher print quality. Most publishers using PostScript use low-cost 300-dpi laser output for drafts and then prints to PostScript-equipped image setters, such as a Linotronic machine, for the final film. It provides low cost proof copies and typeset-quality camera-ready copies have been one of the key ingredients for the phenomenal success of PostScript and its creator, Adobe Systems, Inc. The 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.
