Using netstat I found that my computer was listening on port 631, 
localhost only.

tcp        0      0 localhost:ipp                       *:*             
             LISTEN
udp        0      0 *:ipp                       *:*


I added the following lines to the bottom of  /etc/cups/cupsd.conf

BrowseAddress 255.255.255.255
Listen *:631


The "Listen" argument was by default  "Listen localhost:631"

My macs can print through my linux print server again.
