The Physical Printer column shows the physical printers associated with the printer. To increase the number of physical printers, modify the value in the Number of Physical Printers field.
Increasing the number of physical printers creates a Printer Pool.
Printer Pools - A Printer Pool is a printer with two or more physical printers. They are an effective tool when printing high-volume jobs. When two or more physical printers are configured as a printer pool, RIP-Queue automatically sends jobs to the first printer that is ready. You can also have each physical printer loaded with a different media. This allows incoming jobs to be sent to the printer pool without needing to change the media on the printer.
NOTE: If you cannot increase the number of physical printers, you do not have sufficient Permissions. Contact your sales representative for an upgrade.
