Use the HP EasyColor option for Windows
If you are using the HP PCL 6 printer driver for Windows, the HP EasyColor technology automatically
improves mixed-content documents that are printed from Microsoft Office programs. This technology
scans documents and automatically adjusts photographic images in .JPEG or .PNG format.
HP EasyColor technology enhances the entire image at one time, rather than dividing it into several
pieces, which results in improved color consistency, sharper details, and faster printing.
In the following example, the images on the left were created without using the HP EasyColor option.
The images on the right show the enhancements that result from using the HP EasyColor option.
The HP EasyColor option is enabled by default in the HP PCL 6 printer driver, so you do not need to
make manual color adjustments. To disable the option so you can manually adjust the color settings,
open the Color tab, and click the HP EasyColor check box to clear it.
