I enabled Folder sharing but never succeed. Last night i tried to share my printer and failed again. I tried to contact apple support and they told me everything was fine. I need to reinstall fresh EL Captain. I did it but till the same. I disabled the firewall but no luck. My iMac can't be discovered in network. Do you have the same issue? Any resolution for this? I'm using Wifi to share. iMac 21.5' late 2013 Thanks.
