Understanding attachment types for PSF actual destinations

The attachment type for a PSF DSS actual destination determines what data format is sent and how PSF sends the data to the device or destination. The following attachment types are available:

TCP/IP
A PSF TCP/IP attachment type actual destination drives an IPDS printer that is connected to the network. When sending IPDS to a printer, the PSF DSS uses the PSF printing subsystem to communicate with the output devices. This subsystem provides excellent two way communication with the printer so InfoPrint Manager has the best control and information regarding the job. For more information, see PSF TCP/IP printer.
Note: The InfoPrint 1000 family of printers uses port 9100. Most other InfoPrint printers default to port 5001. The value you set here must match the value set at the printer.
Upload-TCP/IP
A PSF Upload-TCP/IP attachment type actual destination uploads jobs in AFPDS format to either z/OS or MVS. This DSS communicates with either PSF for z/OS or PSF for MVS through the TCP/IP network. Before creating the actual destination, you must determine the Internet Protocol (IP) address of the z/OS or MVS system and the port number at which the AFP Upload Server program on the host system receives requests.
