The Print Spooler Port, also called TCP port 700, is the network port used by networked printers to accept jobs from print servers. By default, the Print Spooler Port is open on most computers, allowing printers to receive jobs sent to them over a network. It is important to note that when a computer receives a job sent over the Print Spooler Port, it is not processed until the print spooler service is started. If the service is not running or disabled, the computer will not be able to accept jobs.
