Comments:       No longer conflicts between the Cups libusb backend 
                and the usblp kernel driver. Built with libusb for 
                hopefully better usb support.
               
                optional: gutenprint or hplip TCEs

                howto:
                $ sudo /usr/local/etc/init.d/cups [start|stop|restart|status]
                the root password needs to be set as root owns /usr/local/etc/cups
                $ sudo passwd
                At some stage in the process below use root and root password 
                Ensure popups allowed in your web browser.

                http://localhost:631/admin will start the browser interface
                Do not click on "Find New Printers", first attempt click "add printer"

Comments:       Howto print from a cups client to cups server
                create a file of the form:
                $ cat /usr/local/etc/cups/client.conf
                ServerName 192.168.1.200
                replace 192.168.1.200 with the ip address of your cups server
                and modify hosts as follows:
                $ cat /etc/hosts
                127.0.0.1 cups_client localhost localhost.local
                192.168.1.200 cups_server cups_server.local
                replace cups_client and cups_server with the hostnames from your client/server
