The Hewlett-Packard Linux Imaging and Printing
project (HPLIP) provides a unified single and
multifunction connectivity solution for HP
printers and scanners (in particular,
HP all-in-one devices).

HPLIP provides unified connectivity for printing,
scanning, sending faxes, photo card access, and
device management and is designed to work with CUPS.

It includes the Ghostscript printer driver HPIJS
for HP printers and a special "hp" CUPS back-end
that provides bidirectional communication with the
device (required for HP printer device management).

It also includes the SANE scanner driver "hpaio"
for HP all-in-one devices. Basic PC send fax
functionality is supported on a number of devices.

The special "hpfax" CUPS back-end is required to
send faxes. Direct uploading (i.e. without print
and scan) of received faxes from the device to the
PC is not supported.

The "hp-toolbox" program is provided for device
management.

The "hp-sendfax" program must be used to send faxes.

The "hp-setup" program can be used to set up
HP all-in-one devices.

The HPLIP project is open source software and uses
GPL-compatible licenses. For more information, see:
