1. Introduction

The ifhp print filter is the latest in a long evolutionary path of print filters for the ifhp printing system. It is intended to unify several different methods of controlling printers, and provide a common code base for future development.

This document is the complete set of references and installation guide for the ifhp printer. It covers the compilation and installation, initial testing, details of system configuration, and various configuration options that would be needed by the system administrator.

The reference for Printer Job Language (PJL) related issues was the Printer Job Language Technical Reference Manual, Hewlett Packard, 10th Edition, October 1997, and the reference for PCL related issues was the PCL 5 Printer Language Technical Reference Manual, First Edition, 1992. These manuals are available through the Hewlett Packard Developers Program. See http://www.hp.com/go/devexchange for information on how to join.

Previous releases of ifhp had a large selection of README files which are now incorporated into the ifhp-HOWTO document.

Current information about LPRng, ifhp and the latest release can be found on the LPRng web page:

Several presentations of LPRng and print spooling software have been made at the Large Scale Installation Administrator (LISA) conferences and are in the ifhp distribution and available on web sites. <tt>ifhp</tt> - An Enhanced Printer Spooler System was presented at the LISA95 conference, and is in the LPRng distribution as LPRng-LISA95.ps. On a more general topic, the slides for the LISA97 tutorial on Printers and Network Print Spooling are also in the LPRng distribution in the DOC/LISA97 directory.
