LPD/LPR Printing
LPD/LPR is an implementation of the standard UNIX line printer daemon which lets you print across a TCP/IP network without the need to install software on your workstation with all filtering and banners done by the printer. Remote printing uses the same commands (lpr, lpq, lpc) as local printing.
The process begins when the lpr call finds a printer on a remote system by looking at the remote (rm) entry in the /etc/printcap file for that printer. lpr handles a print job for a remote printer by opening a connection with the lpd/lpr process on the remote system and sending the data file (followed by the control file containing control information for this job) to the remote system. The printer- based lpd then filters the data and prints the job according to information contained in the control file and its own printcap file.
Printer lpd recognizes the format of a certain printer emulations and filters the data, if possible, so it can be printed on the printer type you specify. You can indicate to the Printer lpd what type of printer is attached to by either:
•Accepting the default port setting (PCL, PostScript and other), or
•Changing the listed emulations via the Telnet or the HTML pages accessed by MAP or WebAdmin.
