First install this device to Network is getting error, LAN switch became crashed after print some documents..try to investigate what wrong. The port protocol that being used was Raw, then changed to LPR and it works fine. Just curious what difference Between LPR and RAW. Here is the definition:
LPR vs RAW
Two common networking computer protocols
are LPR and RAW protocols. Both LPR and RAW protocols are involved with
network printing. The concept of network printing is printing documents
and papers by multiple users without using a direct connection or
cables between computers and printers.
The LPR protocol is a shortened term for Line Printer Remote protocol. The LPR protocol serves as a system
that allows computers and printers to work with each other in a
network. The word “remote” in a whole term implies that a print job from
a computer in another place can be carried out and performed in a
printer that is not in the same space as the other machine as long as
the two are attached to the same network.
The LPR protocol works by using a TCP/IP
connection (transmission control protocol/Internet protocol) and LPD
(Line Printer Daemon). The TCP/IP serves as the channel for the order or
instruction to go from the computer to the printer while the LPD is software
or a program installed inside the computer to allow the user to print a
document or any kind of material using instructions in the computer.
The LPR protocol is initially designed
for the UNIX computers, but it has been used after its development in
other computer systems and platforms. It is often referenced as RFP1179.
It can be used as the protocol for systems that don’t support RAW or
other alternative protocols.
This particular type of protocol
allows print queues since it can receive print jobs from numerous
computers and users. However, in terms of errors, the protocol only
displays a single and undetailed error status report. The example for
this is a dialog box that says “Printer Error” with no specific details
about the said error.
RAW protocol is one of the common
computer languages that documents are translated into and then sent to a
networked printer. The printer interprets the protocol and prints the
document. RAW protocol is used when the computer user wants to print a
complicated document which entails more than texts or letters. The
protocol enables the computer to translate the document into RAW form
before sending it to the printer which understands the given language and job.
The RAW protocol is the default protocol
for systems that do not use Windows OS and for Standard TCP/IP. It is
characterized and known as Port 9100. The advantage of this protocol is
that it sends data without further processing and has smaller packet
headers. The protocol also has fewer networks overhead.
Both RAW and LPR protocols need drivers in order to perform the task of printing the document after the computer gives the command to print.
