LPR or raw for the Network Printing protocol

Network Print Port
Standard TCP/IP Port monitor
The standard TCP/IP port monitor is the best choice for print devices connected to the network.
Standard port monitor enhances LPR (line printer remote, long-range printer),
LPR has been widely used in the past few years as a true standard for network printing. Standard port Monitoring
Faster, more scalable, and 1-way. In contrast, LPR is in all of this

To extend the LPR print 2 functionality, but these changes cannot be combined with the benefits of using standard port monitors
Compare.

The standard port monitor uses TCP/IP as the transport protocol, which makes it a Windows Server
2003 of the preferred port monitor. The standard port monitor also uses the Simple Network Management Protocol (SNMP)
To configure and monitor printer status.

The standard port monitor uses the raw or LPR printing protocol to send documents to the printer. In conclusion, this
Most TCP/IP printers are currently supported by some protocols. Please do not associate these printing protocols with the TCP/IP
or a transport protocol such as Data Link Protocol (DLC).

The raw protocol is the default protocol for most print devices. In order to send jobs in RAW format, the Print service
Service will open a TCP stream for the printer network interface. For many devices, this
The interface will be Port 9100. After the TCP/IP port is created, Windows will follow the RFC 1759
(Printer MIB), using SNMP to query the device's object identifier (Identifier,
OID). If the device returns a value, the system file Tcpmon.ini is parsed to find a match.
If the printer manufacturer provides special configuration information for a specific device, the configuration information is already connected
is created with the configuration settings ready. For example, some external print server interfaces support more than one printer
(for example, Hewlett Packard JetDirect EX with 3 parallel port connections). Manufacturers
You can use different ports to indicate which printer a job should be submitted to (for example,
9102 is submitted to port 1, job 9103 is submitted to port 2, etc.). This feature is necessary for the
A print server interface with a special port name may be useful, for example: on some IBM network printers
Pass port.

The RAW protocol uses ports 9100 through 9102 for printing, and LPR (RFC1179) uses 515-Port connection
To collect the printed data. Depending on the print protocol that the client computer can support, select LPR or RAW.
Port or Queue If you select the RAW protocol, you must enter 9100, 9101, or 9102. If you select
LPR protocol, enter the name of the print queue that consists of English letters. The other computer's print client must
You must use the same port or queue name to share the printer.
The interface printer is connected to the interface of the router, LPT is the parallel port, and USB is the Universal Serial Bus interface.
For example, if the printer is connected to the first parallel port of the router, LPT 1 is selected.
