          <div class="ABSTRACT">
            <a name="AEN21"></a>

            <p>The LPRng; Printing Software consists of the <b
            class="APPLICATION">LPRng</b> print spooler, the <b
            class="APPLICATION">ifhp</b> print filter, and the <b
            class="APPLICATION">LPRngTool</b> graphical user
            interface.</p>

            <p>The <b class="APPLICATION">LPRng</b> print spooler
            is an enhanced, extended, and portable implementation
            of the Berkeley <b class="APPLICATION">lpr</b> print
            spooler functionality. While providing the same
            interface and meeting RFC1179 requirements, the
            implementation is completely independent and provides
            support for the following features: lightweight (no
            databases needed) lpr, lpc, and lprm programs; dynamic
            redirection of print queues; printer pooling and load
            balancing; automatic job holding; highly verbose
            diagnostics; client programs do not need to run SETUID
            root; greatly enhanced security checks; load balancing
            across multiple printers; and a greatly improved
            permission and authorization mechanism. The source
            software compiles and runs on a wide variety of UNIX
            systems, and is compatible with other print spoolers
            and network printers that use the <b class=
            "APPLICATION">lpr</b> interface and meet RFC1179
            requirements. Included in the <b class=
            "APPLICATION">LPRng</b> print spooler distribution is a
            set of customizable banner page generation
            programs.</p>

            <p>The SVR4 lp and lpstat functionality is provided by
            a set of emulator programs, and <b class=
            "APPLICATION">LPRng</b> can be easily integrated with
            the Samba SMB support package. For users that require
            secure and/or authenticated printing support, <b class=
            "APPLICATION">LPRng</b> supports SSL (using <b class=
            "APPLICATION">OpenSSL</b>), Kerberos 5, MIT Kerberos 4
            extensions to LPR, PGP, and simple MD5 based
            authentication. Additional authentication support is
            extremely simple to add.</p>

            <p>The <b class="APPLICATION">ifhp</b> print filter
            converts print jobs into formats compatible with
            PostScript, PCL, text, and other printers and provides
            diagnostic and error information as well as accounting
            information.</p>

            <p>The ;LPRngTool&amp; Graphical User Interface
            provides a simple to use configuration and monitoring
            tool. It allows users to monitor printers and generate
            printcap entries in a simple manner, as well as
            providing extensive help and diagnostics.</p>
