I attempted to print the page
http://www.sipfoundry.org/sipXcallLib/documentation.html with Mozilla 1.4.2 [Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.2) Gecko/20040308], running under Red Hat Linux 9 [kernel Linux dragon.ariadne.com 2.4.25 #1 Thu Mar 4 18:02:19 EST 2004 i686 athlon i386 GNU/Linux]. It printed only one page, labeled "1 of 1" at the bottom, which appeared to be the top of the web page. It looks like Mozilla somehow did not know to break the content up into multiple pages.
This is probably a Mozilla bug, but if it was fairly simple to avoid triggering it, it would increase the usability of the web site.
