HP recommends plain papers with the ColorLok logo for printing
everyday documents. All papers with the ColorLok logo are
independently tested to meet high standards of reliability and print
quality, and produce documents with crisp, vivid color, bolder
blacks & dry faster than ordinary plain papers. Look for papers with
the ColorLok logo in a variety of weights and sizes from major
paper manufacturers.
