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:
