Supported printer drivers for Windows

●PCL 5 UPD

●PCL 6

●HP postscript level 3 UPD

The printer drivers include online Help that has instructions for common printing tasks and also describes the buttons, checkboxes, and drop-down lists that are in the printer driver.

NOTE: The versions of PCL 5 and HP postscript level 3 emulation that are used in this product are identical to the PCL 5 and HP postscript level 3 emulation that are used in the HP Universal Print Driver (UPD) for Windows. It installs and operates in the same manner as previous versions of PCL 5 and HP postscript level 3 emulation, and it does not require any special configuration.

For more information about the UPD, see www.hp.com/go/upd.

HP Universal Print Driver (UPD)

The HP Universal Print Driver (UPD) for Windows is a single driver that gives you instant access to virtually any HP LaserJet product, from any location, without downloading separate drivers. It is built on proven HP print driver technology and has been tested thoroughly and used with many software programs. It is a powerful solution that performs consistently over time.

The HP UPD communicates directly with each HP product, gathers configuration information, and then customizes the user interface to show the product’s unique, available features. It automatically enables features that are available for the product, such as two-sided printing and stapling, so you do not need to enable them manually.

For more information, go to www.hp.com/go/upd.

UPD installation modes

Traditional mode	● Use this mode if you are installing the driver from a CD for a single computer.
	● When installed with this mode, UPD operates like traditional printer drivers.
	● If you use this mode, you must install UPD separately for each computer.

Dynamic mode	● Use this mode if you are installing the driver for a mobile computer, so you can
	discover and print to HP products in any location.
	● Use this mode if you are installing UPD for a workgroup.
	● To use this mode, download UPD from the Internet. See www.hp.com/go/
	upd.

Supported printer drivers for Macintosh

The HP installer provides PostScript® Printer Description (PPD) files, Printer Dialog Extensions (PDEs), and the HP Printer Utility for use with Macintosh computers.
