Internal Program Version: hplip  3.23.8

This package contains the backend drivers and PPDs for printing
with HP printers using CUPS.

HPCUPS is HPLIP's native CUPS printer driver for HP printers.
HPIJS (deprecated) is HPLIP's Ghostscript printer driver for
HP printers, and only used for some Fax devices nowadays.

Install the "hplip" package if you need the proprietary HP plugin
required by some devices, or additional functionality besides plain
printing.
