HPLIP is an HP developed solution for printing, scanning, and faxing with HP inkjet and laser based printers in Linux.
The HPLIP project provides printing support for 1,292 printer models, including Deskjet, Officejet, Photosmart, PSC (Print Scan Copy), Business Inkjet, LaserJet, Edgeline MFP, and LaserJet MFP. (Note: Not all models are currently supported).
The Hewlett-Packard Linux Imaging and Printing project (HPLIP) provides a unified single and multi-function connectivity solution for Linux. The goal of this project is to provide “radically simple” printing, faxing, scanning, photo-card access, and device management to the consumer and small business desktop Linux users. This project is based open source software and uses GPL compatible licenses.
HPLIP is comprised of several major components; applications, driver, backend, daemons, and PPD files. HPLIP is designed to work with the CUPS spooler system. A CUPS/HPLIP system provides bi-directional communication which is necessary for full HPLIP support. HPLIP provides a new CUPS backend called “hp” which supports bi-directional printing connectivity.
HPLIP uses HPIJS for generating printer-ready-data for non-postscript print jobs. HPIJS has been available since 2001 as a uni-directional solution. HPIJS has been modified to support HPLIP, but HPIJS is still backward compatible with existing spoolers. HPIJS is included with the HPLIP solution.HPLIP supports connectivity over USB, parallel and network (JetDirect).
