PDL Data Streaming Port

HP-PDL-DATASTR is a service that facilitates the direct printing of data streams to HP printers. It commonly uses port 9100, allowing for efficient and straightforward communication between devices and printers. This service is widely used in networked printing environments.

What is PDL Data Streaming Port

HP-PDL-DATASTR, also known as the HP Printer Data Stream, is a service designed to handle the direct transmission of print jobs to HP printers. This service typically operates over port 9100, which is a standard port for many networked printers. The primary function of HP-PDL-DATASTR is to enable efficient and reliable printing by allowing devices to send data streams directly to the printer without the need for intermediary steps.

The use of port 9100 for HP-PDL-DATASTR is particularly advantageous in environments where high-volume printing is required. By bypassing traditional print servers, this service can reduce latency and improve overall printing speed. This makes it a popular choice in office settings, educational institutions, and other environments where reliable and fast printing is essential.

HP, a leading manufacturer of printers and printing solutions, has integrated this service into many of its devices to ensure seamless operation within networked environments. The HP-PDL-DATASTR service supports various printing languages and protocols, making it versatile and compatible with a wide range of applications and operating systems. Its widespread adoption underscores its importance in modern printing infrastructure.

PDL Data Streaming Port runs on TCP and UDP port 9100 and is official IANA port.

Security risk

If port 9100 is open and the HP-PDL-DATASTR service is running, it could be exploited by unauthorized users to send print jobs or disrupt printing services. This could lead to the misuse of printing resources, potential data leaks, and denial of service attacks. It is crucial to secure this port with appropriate firewall rules and access controls.

In our UFW tutorial you can follow instructions how you can configure UFW to close port 9100. Use StackChanges to monitor if the PDL Data Streaming Port port is closed and stays closed. StackChanges will send an alert if port 9100 is open again.
