Not currently.  The best chance of seeing this changed is to file an  
Apple bug report asking for the default profile to be relaxed to allow  
writes to /Users/Shared:

The backend - when CUPS sees the backend as executable only by root,  
it will run it as root.

Yeah, you don't want to do that, and it won't help since the sandbox  
profile prevents writes to /Users.
