DevicesTroubleshoot a Remote Spooler (LPR) Connection

If you encounter a problem when attempting to configure a remote spooler (LPR) connection by using a TCP/IP device connection with LPR protocol, do the following to troubleshoot the issue.

Note: Before you can use a remote spooler (LPR) connection with Loftware Enterprise SP, you must configure the client computer to support such connections. For more information, see Requirements for Loftware Enterprise SP Client Computers.

Important! Whenever you add a new device, data service, integration, or facility, you must ensure that the service is activated on all Loftware Application Servers on which it should be available to run and started on at least one. In an environment with only one Loftware Application Server, these types of services are automatically activated and started when they are created. For more information, see High Availability with Distributed Services.

Important! In an environment with distributed services, to permit a user to perform administrative tasks related to services you must assign Read and Write permissions for Servers. These permissions must be assigned for each server in Access Control Access Control. Examples of administrative tasks related to services include creating a data service, a device connection, an integration, or a facility. Core services can only be configured by the SuperAdmin or SystemAdmin user.

  1. Test the device connection to diagnose the issue.
    1. In Loftware Enterprise SP, click Devices Devices.
    2. In the All Devices pane, click the device for which there is a problem.
    3. On the Connection tab, click Test Connection.
    4. Review the message displayed.
  2. On the Connection tab, verify that the IP Address field contains an IP address or DNS name, not the name localhost.
  3. Verify that the computer to which the device is connected is accessible via IP address or DNS name.
  4. Verify that the computer to which the device is connected has been configured to allow Loftware Enterprise SP to use a remote spooler (LPR) connection. For more information, see .
  5. In Control Panel, click Administrative Tools and double-click Services. Ensure that the LPD Service is running.
  6. In Control Panel, ensure that the driver used by the device is Windows Generic/Generic Text Spooler.
  7. Review the Windows Event Log for relevant events to diagnose the issue.
    1. In Control Panel, click Administrative Tools and double-click Event Viewer.
    2. In the Event Viewer, click Custom Views and then click Administrative Events.
    3. Review the details of events for which the Source is Spooler-LPDSVC and the Event ID is a number from 4000 through 4009.
    4. If the Event ID is 4009, note whether the name of the device shown in the event is as expected.
  8. If the device name was entered correctly but does not appear to be valid, it may be necessary to configure a registry value in the Windows Registry on the computer to which the device is connected.
    1. In the Registry Editor, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print.
    2. If the DnsOnWire registry value exists, set its value data to 1. If it does not exist, create a new DWORD (32-bit) Value named DnsOnWire and set its value data to 1.
