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).
