Thanks. I looked through the documentation and it didn't talk about using the CUPS server web interface, only the YaST one. So I deleted the printers in the YaST interface and then remade them. A note to those who may have the same problem as I did, the hostname and workgroup isn't import into the link propertly in the YaST interface. It ends up looking like
smb://home.ad.uni.edu/hostname/printer
which it shouldn't be
smb://hostname.home.ad.uni.edu/printer
hope it helps
