Printer-Specific
Differences
Introduction
Each Hewlett-Packard printer implements minor variations of PCL 5
in order to best suit its intended use. This chapter describes specific
differences that are important when developing applications for the
various PCL 5 printers. The sections in this chapter describe such
information as new commands not contained in the PCL 5 Printer
Language Technical Reference Manual, and other miscellaneous
differences in PCL operation particular to that printer.
Note For information about products newer than those included in this
book, see the PCL5 Comparison Guide Addendum, which includes
product-specific information about newer products, as well as
commands and variables added to support these newer products.
HP LaserJet III and IIID Printers
With the introduction of the HP LaserJet III printer, Hewlett-Packard
introduced the PCL 5 printer language. The PCL 5 printer language
incorporated many new features over the PCL 4 language. A few of
the more significant features included such things as the addition of a
scalable font technology, HP-GL/2 vector graphics language support,
print model features, raster graphics enhancements, and the Print
Direction command.
The HP LaserJet IIID printer language support is basically identical to
the HP LaserJet III printer except for the addition of the duplex
feature, dual input bin, envelope feeder support and their associated
commands (see Table 1-1).
