I had a working 7.0 system. I then upgraded this to RC2. After the upgrade, the /etc/printcap was replaced by setup. This required running /usr/bin/printtool to remove the "old" definition and (re)install a print definition. The defined printer is a LPD server on another linux host. There should be something to convert the old format /etc/printcap into what is expected by the new printconf tool. This is against setup because setup "owns" /etc/printcap but maybe should be against printconf or anaconda.
This defect considered MUST-FIX (show-stopper) for Florence GOLD release.
This is as fixed as it's gonna get.
