CentreWare Printer Drivers 1-5
Types of Printer Drivers
The CentreWare printer drivers are available in PostScript 3, PCL 5e, and PCL 6 (XL)
printing formats.
PostScript
PostScript gives you greater ability to scale and manipulate images; it offers more
precision with high-end graphics. PostScript also provides you with different types of
error-handling and font substitution options.
PCL
PCL (Printer Command Language) generally has fewer advanced features than
PostScript. However, using PCL enables you to process most jobs faster.
N OTE : A PCL 6 driver for Windows NT is not available with this
CentreWare release.
