Prerequisites for installing the DCA and Cloud Connector agent

The necessary prerequisites for installing the DCA and Cloud Connector agent are:

Hardware

Minimum configurations

• Processor: Dual-Core 1.7GHz

• Memory: 4gb or higher

• Disk space: 10gb or higher

Recommended configurations

• Processor: Octa-Core 2.6GHz

• Memory: 16gb or higher

• Disk space: 60gb or higher

Software

Minimum configurations

• Microsoft .NET Framework: version 4.7.0 or higher.

• Microsoft .NET Runtime: version 8.0.21 or higher.

• Microsoft ASP.NET Core Runtime: version 8.0.21 or higher.

• EpsonNet SDK for Windows: for monitoring Epson printers connected via USB, the EpsonBidirectionalService service (installed via the EpsonNet SDK for Windows application) must be running.

• NDD - Queues Monitor: a component integrated with the DCA and Cloud Connector agents, required for the NDD - Supply Watch service to function.

During the installation process on Windows, the installer will automatically check whether NDD - Queues Monitor, Microsoft .NET Runtime, Microsoft ASP.NET Core Runtime, and EpsonNet SDK for Windows are already present on the computer. If any of them are not present, the installation will be performed automatically.

Do not uninstall Microsoft .NET Runtime and Microsoft ASP.NET Core Runtime, and do not stop the EpsonBidirectionalService service. These components are essential for the proper functioning of the DCA and Cloud Connector agent and its associated services.

Incompatibilities

• NDD Print Agent: versions 5.25 through 5.30.
  The DCA and Cloud Connector is not compatible with versions 5.25 through 5.30 of the NDD Print Agent. To install or update the DCA and Cloud Connector in environments using these versions, you must first update the NDD Print Agent to version 5.31.0 or later. After updating the NDD Print Agent to a compatible version, you can perform the installation or update of the DCA and Cloud Connector as usual.

Environment

Minimum configurations

• SNMP communication enabled for communication with printing devices: Ports 161 and 162 - UDP.

• NPAP communication enabled for communication with printing devices: Ports 9300, 9301, 9302, 9500 and 9501.

• UDP communication enabled for communication with Zebra thermal printing equipment to collect alerts: Port 50501 - UDP.

• HTTP communication enabled for processing EcoPrint print jobs: Port 58564 - TCP/IP.

• Internet communication enabled for communication with NDD Orbix:

  • Proxy: Port 443 - TCP/IP: for proxy communication with the portal.

  • Gateway:

    • Port 9635 - TCP/IP: for agent communication with the gateway. The port must be enabled on the internal network to allow the agent and services to view the Gateway Connector.

    • Port 443 - TCP/IP: for gateway communication with the portal. The port must be enabled for external access only on the computer/server where the Gateway Connector will be installed.

For more details on how the communication flow takes place, go to Configure the DCA and Cloud Connector agent.

Web service

• Web service used by DCA and Cloud Connector to receive/send data:
  DataCenter Global and DataCenter Europe: http://agent.nddorbix.com.
  Sends application monitoring data (server, services, and logs) to NDD Orbix.

Raspberry Pi

• Device model: Raspberry Pi 3 Model B or higher.

• Operating system: Ubuntu 24.04 or higher (64-bit).

• Storage: 8gb microSD card or higher.

• Connection: local network that allows communication with the NDD Orbix server services.

Startup Type (ST)

• DCA and Cloud Connector: Automatic.

• Attached services: Manual.

Services installed with DCA and Cloud Connector remain with the Startup Type (ST) set to Manual, as the responsibility for starting and stopping these services lies solely with the agent itself. Only DCA and Cloud Connector should have the ST set to Automatic.

Starting with version 1.2.0, the DCA and Cloud Connector agent automatically checks the ST of each service. If it identifies any service configured as Automatic, it will automatically be adjusted to Manual.

Do not change the TI of services to Automatic, as this may compromise the correct functioning of the agent and its associated services.

HP USB printers

• Check the Enable PJL Device Access Commands option in the Security > General Security of device web section to ensure proper monitoring of HP USB printers.

EcoPrint

• PCL6 language driver.

To ensure the solution functions correctly, NDD Orbix components automatically monitor and adjust certain configurations in the print queues.

The NDD - Queues Monitor component automatically monitors and configures the following parameters:

• Advanced tab in the driver properties:

  • Start printing after last page is spooled: enabled.

  • Print spooled documents first: enabled.

  • Keep printed documents: disabled.

• Sharing tab in the driver properties (for shared queues only):

  • Render print jobs on client computers: disabled.

The NDD - Supply Watch service automatically monitors and configures the following parameter:

• Advanced tab in the driver properties:

  • Enable advanced printing features: disabled. If this option remains enabled, the driver language may change during printing, preventing the savings from taking effect.
