  Line printer - Wikipedia, the free encyclopedia
The line printer is a form of high speed impact printer in which a line of type is printed at a time.
In a typical drum printer design, a fixed font character set is engraved onto the periphery of a number of print wheels, the number matching the number of columns (letters in a line) the printer could print.
As with the drum printer, as the correct character passed by each column, a hammer was fired from behind the paper.

 LWN.net: Paper: Examining Remote OS Detection using LPD Querying
This paper tries to describe a way of using the line printer daemon ("lpd") as a knowledge base with which we can determine a possible Operating System on the remote host.
It is important to realize that when fingerprinting daemons, you are actually fingerprinting at the application level, whereas when you are fingerprinting the TCP/IP stack, you are fingerprinting at the kernel level (default window-sizes, ttls, etc).
Line Printer Daemon OS Fingerprinting (A) Theoretical Analysis The theory behind this concept lies within the boundaries of RFC 1179 (Line Printer Daemon Protocol).

 Technical Memo: LPD NOTES
RFC 1179, Line Printer Daemon Protocol states that it is "..not a standard..".
Familiarity with the particular implementation of line printer daemon as well as a familiarity with the concepts in RFC 1179 will aid you immeasurably.
Line printer daemons can process many different types of job streams depending on the implementation (at least in theory).

Printers may be started or stopped as necessary and reports may be halted and then restarted from the last page printed or any line within the report.
Each printer defined has a specified maximum number of lines allowed to prevent reports which exceed this number from printing on the printer.
Printer translation tables are available to convert certain hexadecimal characters in the report to prevent hardware errors.

 LPRng-HOWTO: RFC 1179 - Line Printer Daemon Protocol
However, on some systems which are acting as servers for a large number of printers even increasing this port range is insufficient, and steps need to be taken use the originating port numbers more efficiently.
The request consists of a single octet indicating the request type, followed by the printer (or print queue) name, followed by a set of options for the request, followed by a LF (line feed) character.
The file transferred by the sender is simply the command lines that it would have normally sent for job transfer, followed by the control or data file values.

 Line Printer Daemon protocol - Wikipedia, the free encyclopedia
The Line Printer Daemon protocol/Line Printer Remote protocol (or LPD, LPR) also known as the Berkeley printing system, is a set of programs that provide printer spooling and network print server functionality for Unix-like systems.
program provides the daemon and queues with which the aforementioned commands interface.
A printer that supports LPD/LPR is sometimes referred to as a "TCP/IP printer" (TCP/IP is used to establish connections between printers and workstations on a network), although that term seems equally applicable to a printer that supports CUPS.

 Security problems in the lpd protocol
The syntax is: U filename [LF] Therefore, by inserting the line: "U/vmlinuz" into the control file you will cause the Linux kernel to be removed from the file system.
The syntax is: M username [LF] Therefore by adding the line: "Mjoeuser@www.somewhere.com" you will cause joeuser to receive mail notification about the print job.
These holes are due to the implementation of the lpr protocol and the fact that lpd runs as root.

For printers which provide status information over a bidirectional connection, it can monitor the printer for conditions and report current page usage.
By default, IFHP uses the Unix file utility to determine the input job type, then uses various conversion programs including GhostScript (www.ghostscript.com) to convert the file to the appropriate format for a printer, and then transfers the job to the printer.
