In short, you can't.  Comments inline.

/etc/printers.conf and ~/.printers are used by the Solaris LP  
implementation, not CUPS.  CUPS *can* be configured to generate the / 
etc/printers.conf file via the Printcap directive - just use  
"Printcap" with no value in /etc/cups/cupsd.conf to disable it.

As for the remote.cache file, there is no way to disable it short of  
disabling browsing.
