Created especially for use in all-in-one machines—both inkjet and laser—HP All-in-One Printing Paper is heavier, thicker and brighter than ordinary multi-use papers and has a brilliant blue-white shade for higher contrast documents. It incorporates HP's proprietary ColorLok technology that helps reduce smears, while producing blacks up to 40-percent bolder and uniform colors that are up to 10-percent more vivid than ordinary papers.
