If you don't have LPRng installed, you can't update it.  "yum update"
only updates things that are already installed.

All updates for Red Hat Linux 9 come from Fedora Legacy.  You can get
them by using yum or apt-get.

Just install it (you can use "yum install LPRng"), then use the Printing
applet in System Tools to switch to it.

There really isn't any good reason to switch to LPRng from CUPS.  Your
problem should possibly be squawked to the CUPS people.  However, since
you run an obsolete version of Linux, you may not get a lot of help.  I
really, REALLY suggest you go to Fedora Core 2 or 3 ASAP.
