Explanation:
You can create a printing pool to automatically distribute print jobs to the next available printer. A
printing pool is one logical printer connected to multiple printers through multiple ports of the print
server. The printer that is idle receives the next document sent to the logical printer. This is useful in
a network with a high volume of printing because it decreases the time users wait for their
documents. A printing pool also simplifies administration because multiple printers can be managed
from the same logical printer on a server.
