Printers requiring additional extensions to operate with CUPS

Following is a list of printers that have been found to require additional extensions in order to operate with CUPS. These extensions are not listed as dependencies of CUPS and so are not automatically downloaded or loaded with the cups.tcz. These extensions must be individually added to OnBoot using AppsAudit, or loaded using AppBrowser. If the latter CUPS will need to be retstarted after they are loaded (/usr/local/etc/init.d/cups restart)
