1. The Common Unix Printing System provides a portable printing layer for UNIX(TM) operating systems. It has been developed by Easy Software Productsto promote a standard printing solution for all UNIX vendors and users. CUPS provides the System V and Berkeley command-line interfaces. This is the main package needed for CUPS servers (machines where a printer is connected to or which host a queue for a network printer). It can also be used on CUPS clients so that they simply pickup broadcasted printer information from other CUPS servers and do notneed to be assigned to a specific CUPS server by an/etc/cups/client.conf file.
