This package contains PPD (printer definition) files for the printers supported through the HP Linux Printing and Imaging System HPIJS driver. . These PPDs should work well with the matching versions of HPLIP and HPIJS, but may not be the most up-to-date PPDs available for a given printer. See http://linuxprinting.org/ for the latest version of the PPDs (which are not guaranteed to work well).
