1. HP OfficeJet Linux driver (hpoj) This software provides Linux support for most "multi-function" (or "all-in-one") peripherals from Hewlett-Packard, including OfficeJet, LaserJet, and Printer/Scanner/Copier ("PSC") products. It consists of: - Low-level drivers and libraries to communicate with the device. Depending on your hardware and operating system configuration, you may connect devices directly to your workstation with a parallel port or USB (Universal Serial Bus), or to a LAN (Local Area Network) using certain models of HP JetDirect print servers. - An application programming interface (API) known as "PTAL" (Peripheral Transport Abstraction Library) that hides the differences in accessing devices connected via parallel, USB, or JetDirect. - Printing support, largely powered by ghostscript, the HP inkjet driver (for selected models), and one of various print spoolers (Berkeley lpd, gnulpr, LPRng, CUPS, PDQ, etc.) that may already be installed on your computer. - Scanning support, powered either by Scanner Access Now Easy (SANE) or by "ptal-hp scan", a command-line application provided with the hpoj package. - Graphical and command-line applications to access various features of the peripheral, such as displaying status of the device and setting the clock.
