I have a iMac using Mac OS X 10.6. I reset my HP C4400 printer in the Print & Fax directory of System Preferences, because it was showing as offline and i thought this might solve the problem. When i went back to try and add the printer again it doesn`t show up anywhere. I tried uninstalling and reinstalling the latest Hp drivers and software, i also did the usual mac maintenance, but my mac still doesn`t recognize it. Any suggestions?
