I've been having a look at printers installed on a windows 2003 print server. If you get the printers IP and do a port scan, 9/10 they've got snmp (blank or default community string), telnet, ftp (anonymous) open? What ports and services are the real ones needed for network printing and which can usually be disabled?

Hi cf090, Thanks for post here. Mr x may provided a good article that would answer your question. Meanwhile, the Print Spooler service is the center of the Windows printing subsystem, I had list the required protocol and ports of this service below for you reference : System service name: Spooler Application protocol Protocol Ports NetBIOS Datagram Service UDP 138 NetBIOS Name Resolution UDP 137 NetBIOS Session Service TCP 139 SMB TCP 445 Note The Spooler service uses RPC over named pipes. This service has the same firewall requirements as those of the "File and Printer Sharing" feature.
