Configure cupsd.conf for local root access without password

[Stephen]

I'm fairly new to CUPS and am grappling with the authentication side of things.

This is what I'm trying to do.
1.  Control access to the Web Interface with a single username/pwd.
    This will be used by Admin folks only.

2.  Allow local user ROOT to enable/disable printers from the command line without password prompt.

3.  Allow remote servers to send print requests to the CUPS server.
    For this I'm using a Perl module Net::Printer.

I have the following:
   <Location /printers>
       Order deny,allow
       Deny from all
       AuthType Digest
       Require valid-user
       Allow from 10.182.25.*
   </Location>
Remote UNIX servers cannot send to CUPS, but the Web Interface correctly prompts for a username/pwd.

If I have:
   <Location /printers>
       Order deny,allow
       Deny from all
       Allow from 10.182.25.*
   </Location>
then my remote UNIX servers can send to CUPS correctly, but the Web Interface is not protected.

Also, what do I need to prevent the accept/disable commands prompting for a password at the Local command line?
