What is the TCP/IP Printing Service?
The TCP/IP Printing Service is a printing service provided for integration into Unix environments. TCP/IP Printing Service is based on the Berkeley remote printing protocols commonly called Line Printer Daemon (LPD) and Line Printer Remote (LPR). These are described in RFC 1179. TCP/IP Printing Service is not the same thing as the native Windows NT and Windows 2000 printing services (SPOOLSS). Although the native Windows NT and Windows 2000 printing services do operate in a TCP/IP environment, they operate using a different protocol. The native Windows NT and Windows 2000 printing services are not affected by this vulnerability.
