HP EasyColor optimizes results
Make a statement with high-impact, professional-quality color documents. Use HP EasyColor to manage
settings for maximum impact. 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. You can expect glossy text, bold graphics, and vivid images. And, you can count on consistent color—
page after page, document after document, and ink cartridge after ink cartridge. Use HP Web Jetadmin and the
HP Universal Print Driver to manage color use and protect your color investment.

HP all-pigment inks offer vivid, highly saturated colors and bold blacks. They provide benefits over traditional
dye-based inks, including superior water and fade resistance and better durability. These unique qualities are
possible because the pigment solid does not dissolve in water but is dispersed to prevent pigment settling. As a
result, the printed output resists rain, water spills, and highlighter-pen smearing, and you can handle important
documents with confidence.
For even better print quality, we recommend papers with ColorLok® technology. ColorLok papers are engineered
with special additives that result in faster drying time, and minimal show-through on your printed page, which
means that you don’t have to sacrifice readability or image quality when printing on both sides of the paper.
The printer supports a wide range of paper types, including HP Glossy and Matte Brochure media as well as
advanced photo media and other inkjet specialty papers.
Archive with confidence
This printer’s ink has achieved ISO 11798 certification.
10
This rigorous standard ensures that printouts have a
certified durability for wear and tear, often referred to as “archiveability.” You can rest assured that the quality
and readability of prints will remain high for years to come.
