HPLIP (HP Linux Imaging and Printing) is a complete single and multi-function printing device connectivity solution for users of Linux. Supported features include a toolbox with status and maintenance functions, scanning, a CUPS backend that supports bidirectional I/O, and photo card unloading. It includes HPIJS 2.x and supports over 1000 HP printer models including Deskjet, Business Inkjet, Photosmart, Business Inkjet, PSC, Officejet, Mono/Color LaserJet, and LaserJet Multifunction Peripheral (MFP).
Optar is a software codec that generates 2D bar codes for data storage on paper using a black and white laser printer and scanner. It fits 200kB on an A4 page, uses Golay forward error correction codes to ensure reliability, and can also be used to store data on photographic film.
Garbure is a collection of dedicated distributions. Each distribution provides carefully selected tools for a specific target domain, and is completed with examples and documentation. The set of distributions forms an entity, but each distribution works also on its own. All elements are arranged in the same way for each distribution.
The HP OfficeJet Linux driver provides printing, scanning, and photo-card access support for most Hewlett-Packard multi-function peripherals connected to a parallel port, USB port, or LAN via selected HP JetDirect print servers. Additional applications are provided to view the contents of the front-panel LCD and to access other control and status features of the device.
