I also get the cupsdAuthorize: Local authentication certificate not found! Last week I was able to print to my HP1020 and my HP 5L which was installed on my wife's Windows XP box. Then I nuked Windows, installed Edubuntu (fiesty), and it also worked. Then I wanted to do some file sharing and installed Samba, and suddenly my printers stopped working. I cannot get either of them going on my Edubuntu box, or on my Ubuntu box which has samba installed.
Today I tried to remove Samba completely, but I was still not able to get the printer going. Is there any way I can resolve this issue?
