The ifhp program is an enhanced, extended, highly configurable, and portable implementation of a print filter for use with the LPRng Print spooler package. ifhp supports network, serial, and parallel printers, does page accounting and job recovery, and allows an extremely high level of configuration and tuning. ifhp gets its flexibility by using a configuration file to set its operational characteristics. The configuration file can contain multiple separate printer configurations and the configuration selection is done by a very simple command line option. The filter supports text, PostScript, PCL, and PJL printers, and can be configured to handle a wide range of printer quirks and mis-implementations.

1. Introduction

The ifhp Print Filter is the primary print filter for the LPRng Print Spooler. This document is designed to be the single basic reference for the ifhp software; the LPRng software is distributed separately and has additional documentation.

2. Acknowledgements

I would like to thank all of the LPRng users who so relentlessly tried the incredible number of permutations and combinations of printers and software, and whose requests for just one more feature led to the development of the software.

3. Shell Prompts

The following table shows the default system prompt and superuser prompt. The examples will use this prompt to indicate which user you should be running the example as.

1. Introduction

The ifhp Print Filter is the primary print filter for the LPRng Print Spooler. This document is designed to be the single basic reference for the ifhp software; the LPRng software is distributed separately and has additional documentation.

2. Acknowledgements

I would like to thank all of the LPRng users who so relentlessly tried the incredible number of permutations and combinations of printers and software, and whose requests for just one more feature led to the development of the software.

3. Shell Prompts

The following table shows the default system prompt and superuser prompt. The examples will use this prompt to indicate which user you should be running the example as.

User Prompt
Normal user %
root #

4. Typographic Conventions

The following table describes the typographic conventions used in this book.

Meaning Examples
The name of commands, files, and directories. On screen computer output.

Edit your .login file.

Use ls -a to list all files.

    You have mail.

Emphasis You must do this.
Command line variables; replace with the real name or variable. To delete a file, type rm filename
Environment variables $HOME is your home directory.

5. Notes, warnings, and examples

Within the text appear notes, warnings, and examples.

Note: Notes are represented like this, and contain information that you should take note of, as it may affect what you do.

WarningWarnings are represented like this, and contain information warning you about possible damage if you do not follow the instructions. This damage may be physical, to your hardware or to you, or it may be non-physical, such as the inadvertant deletion of important files.

Examples are represented like this, and typically contain examples you should walk through, or show you what the results of a particular action should be.

Chapter 1. Introduction

The ifhp print filter is the latest in a long evolutionary path of print filters for the LPRng print spooler system. It unifies the low level printer communication facilities and provide a common code base for future development.

This document is the complete set of references and installation guide for the ifhp print filter. It covers compilation, installation, initial testing, details of system configuration, and configuration options that would be needed by the system administrator. Previous releases of ifhp had a large selection of README files which are now incorporated into the IFHP Reference Manual.
