Requirements
- You must have a functional Service Client that meets the minimum required specifications. See Service Client Setup.
-
Your Service Client must be able to access the following service URLs adjusted for your region.
https://agent-api.app.printercloud.com.https://agent-api-grpc.app.printercloud.com.ofn.app.printercloud.com.ofn-gw.app.printercloud.com.
- Source application must be able to reach the Service Client over port 515.
SAP Configuration
Vasion Output supports connections to SAP's on-premises and private cloud version editions.
Here are some additional details about configuring Vasion Output with SAP.
- The SAP Spool Server connects to the Service Client through port 515. If you change the port number, you also need to update SAP.
Ubuntu Service Client
Customers with an Ubuntu (LTS) 22.04 Service Client must run an additional command on the Service Client after configuring the steps below. The command initializes the service.
sudo ln -s "$(cat /etc/pl_dir)/service_client/service-output-management/bin/libmako-adapter-lib.so" "$(cat /etc/pl_dir)/service_interface/lib/libmako-adapter-lib.so" The following steps show how to configure LPD in the Vasion Print Admin Console. You may need additional settings configured within the EMR / ERP. Use the assistance of a Product Support Engineer or an assigned System Engineer for proper configuration.
Turn On the LPD Service
- In the Admin Console, select the Service Client where you want to configure LPD Service.
- Select the Output Automation tab.
-
Enter the Domain Name of the Service Client machine.
This Domain Name must match the device certificate name and the Service Client must map this Domain Name to its local IP address. If this field is empty, the service will fail to start, and adds a "Failed to get host address" to the log.
-
Scroll to the LPD service section and select the Enable LPD Service option.
-
Enter the port number for LPD Service Client. The default is port 515.
-
- Select Save in the upper-right corner.
The Status section shows a green circle and states the service is Online when everything is configured correctly.

Troubleshooting Help
In some setups, external applications may need to reach the Vasion OutputService Client using a DNS name that resolves to an external IP address. However, this can cause issues the following issues:
- The Service Client cannot resolve the DNS name to its internal IP address.
- External DNS resolution conflicts with internal requirements.
Check if the Service Client can resolve the DNS name to its internal IP address. If the DNS name doesn't resolve correctly, you may need to modify the hosts file. See Troubleshoot DNS Resolution for Output Automation-Service Client
Ensure that the DNS name in the UI matches the one in the certificate used by the Service Client.
