CUPS 1.61 with no authenication

I have been working with CUPS 1.61 and have got the WIndows Point n print printing running fine however I have issues with nn authenticated CUPS printing. One machine has a CUPS virtual PDF printer (server) and the other is set to automatically detect CUPS printers on the network (client). When I go to print I get a dialog on client saying "none" and asking for a password. I assume the none" refers to a username but not sure and no password seems to work. What I really want is to completely disabke authentication, but have noty figured out how. At this point the cupsd.conf is default.

I am not sure how todo this and in the cups web gui I set to users to "all" as well as have tried various other settings,and noting seems to work.
