Before upgrading to v.7 from v.6, I didn't remove LPRng rpm. In v.7 I installed the new version of LPRng, but didn't work. (It appears "page not found" when clicking on "Printerqueue Admin"). Now I've removed with yum both LPRng I installed and the printers option in server-manager's menu has disappeared. I installed LPRng again, with no result. I don't know what to do to recover printers in the menu, and to get LPRng working again. I need some help. Thanks.
