First, AFAIK, CUPS provides several autthentication methods for the clients 
to authenticate against the cups server, not against individual printers.

Second, there is a technical issue: the autentication Konica Minolta uses 
for the bizhub Cxxx printers (MFC devices, essentially), uses a proprietary 
encryption method for the user name and password combination which requires 
a proprietary client application to submit "secure" print jobs. And this 
proprietary software is only provided for Windows platforms (2000 and up).
