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.
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).
