Print server services are the software on the Windows NT print server that receive print jobs from specific types of network clients, determine whether the spooler should alter them, and then send them to the spooler by calling the spooler application program interfaces (API).
Each print server service uses different programmatic logic and makes different assumptions about print jobs from its supported print clients. These differences are detailed in the sections describing each service.
Windows NT Workstation provides the following print server services:
Client applications on the Windows NT Workstation print server itself use these additional software modules:
The following table lists each print server service and the type of print client processed by the service.
