See if you can use the APW (add printer wizard) - network printer - browse for the printer and see if the printer shows up in your domain/workgroup and you can just select the printer which is the 'local port' If you can't locate the printer by browsing the network, it would probably be a better network if you could fix the browsing problem but the \\ip_address_of_centos_system\printer_share_name and the printer_share_name would be the exact name of your printer as you set it up in cups (hopefully without spaces). If you have set mime.types and mime.convs to allow 'raw' printing then that is your 'raw' print queue Craig
