The lpr line-printer system supports:
- multiple printers
- multiple spooling queues
- both local and remote printers
- printers attached via serial lines that require line initialization (e.g., baud rate)
To print a file using the line-printer system, you need:
- a user interface and a method of organizing and preparing print jobs
- spooling directories, somewhere to store files waiting to be printed
- a way of preventing unauthorized access
- for remote printing, a network manager capable of delivering the files to be printed
- some knowledge about the printer being used
Note:
You need to log in as root to set up the lpr system.
