The nonsystem HP-GL/2 driver supports a variety of HP-GL/2 pen plotters and ink jet plotters.
This is a generic HP-GL/2 driver that is not optimized for any particular manufacturer's devices. For example, it does not send PJL commands to devices, as a true Hewlett-Packard driver would. The HP-GL/2 driver supports obsolete pen plotters and newer devices made by manufacturers other than Hewlett Packard.
When a Hewlett-Packard DesignJet device was configured, the System Printer option should have been used. Hewlett-Packard redesigned its print path to use the Windows system printer. You can get excellent print speed and quality through the system printer.
You can use this HDI driver if you use a device that emulates an HP plotter and uses HP-GL/2. Follow the device manufacturer's recommendations for switching your plotter to the correct emulation mode. You can also shift your plotter to HP-GL/2 mode by providing a pre-initialization string in the Plotter Configuration Editor.
