Infor LN Reports Stuck in the Print Queue: Device and Spooler Fix
infor ln report stuck in print queue device offline
Also searched as
- infor ln print job not printing
- baan device offline error printing
- infor ln spooler not sending to printer
- infor ln report writer output stuck queued
Short answer
Infor LN reports and forms stay queued and never reach the printer when the target device definition points to a printer that is offline, or the print listener on the print server has stopped. Check the device's status in Common > Printing > Devices, confirm the underlying OS printer is reachable, and restart the print listener if jobs remain queued after the printer itself is fixed. Most cases trace back to a genuinely offline printer, not an LN bug.
Applies to: Infor LN 10.x printing and report management (Report Manager, device-based printing); applies to physical, PDF and preview device types
Clear a stuck print queue and get output flowing again
- 1Open Common > Printing > Devices and check the status and definition of the device the stuck report is targeting.
- 2Confirm the physical printer or print server share behind that device definition is actually online and reachable from the LN application or print server, not just from a user's workstation.
- 3Check whether the print listener or spooler process on the print server, the component that pulls queued jobs from LN and sends them to the OS print queue, is still running.
- 4Look at the OS-level print queue on the server for the target printer; jobs can be stuck there (paused, in an error state, out of paper or toner) even after LN has handed them off successfully.
- 5If a specific device consistently fails, test with a different, known-good device definition to isolate whether the problem is the device definition or the printer and network path itself.
- 6Restart the print listener service if it has stopped, then confirm previously stuck jobs either resume automatically or need to be resubmitted from the report's own history.
- 7For reports rendered through Report Writer, SSRS or a PDF output device, confirm the rendering service itself is running, since a stalled rendering step can look identical to a stuck print queue from the user's side.
How LN printing is put together
Infor LN does not send output directly from a session to a Windows or network printer. It writes the job to a device, a logical definition mapping to a physical printer, a PDF file location, a preview window, or an external rendering engine such as SSRS. A print listener process on the designated print server picks up jobs queued for physical devices and forwards them to the OS print queue.
This layered design means a stuck report can fail at any of several points: LN never queued it, the device definition points somewhere invalid, the listener is not running, or the OS-level printer itself is offline or in an error state. Working through the layers in order, LN queue, listener, OS queue, physical printer, finds the actual break point fastest.
Device definitions versus the physical printer
A device definition in Common > Printing > Devices is just configuration, it has no awareness of whether the underlying printer is actually turned on or reachable. If a printer is replaced, renamed, or moved to a new print server, the device definition has to be updated manually; LN will keep queuing jobs against a device pointing at a printer that no longer exists.
This is the single most common real-world cause of a stuck queue: an IT change to printer infrastructure, a print server migration, a renamed share, a firmware update that changed the printer's network name, that nobody reflected in the corresponding LN device definition.
When it is a rendering problem, not a printing problem
For sites using SSRS or another external rendering engine for report layouts, a job can appear stuck in the print queue when the actual holdup is the rendering service failing to generate the output in the first place. Check the rendering service's own status and logs separately from the print listener if the device and printer both check out fine.
Common pitfalls
- !Only checking whether the printer is reachable from a user's desktop, rather than from the LN application or print server itself, which may be on a different network path.
- !Restarting the entire LN application server to fix a printing problem when only the print listener service needed a restart.
- !Not updating the device definition after a printer or print server change, leaving jobs queuing against a target that no longer exists.
- !Missing an OS-level print queue that is paused or in an error state, after confirming the printer itself has power and paper.
- !Treating a rendering engine failure, for SSRS or similar, as a printing problem and troubleshooting the wrong component.
How an ERP-grounded AI assistant handles this
For a recurring printing issue, a grounded LN assistant can pull the device definition, the print listener's last known status and the OS queue state into one answer when a user reports a stuck report, instead of the help desk walking through each layer manually for every ticket. Over time it can also spot patterns, for example the same device failing after every print server change, and flag it to the admin before the next report gets stuck too.
Frequently asked questions
Which session manages printer devices in Infor LN?
Common > Printing > Devices defines the logical devices that LN sessions and reports print to, including the device type, physical printer, PDF, or preview, and, for physical devices, the print server and OS printer it maps to.
Why does printing work for some users but not others?
Users are often printing to different device definitions, either their own default device or one chosen at print time. If only some users are affected, compare the specific device each of them is targeting rather than assuming a site-wide printing outage.
Do I need to restart LN to fix a stuck print queue?
Usually not. The print listener or spooler service on the print server, and the OS print queue for the specific printer, are almost always enough to check and restart. A full LN application server restart is rarely necessary for a printing issue alone.
How do I stop this from recurring after printer infrastructure changes?
Build a step into your IT change process that includes updating the relevant LN device definition whenever a printer, print server, or network printer name changes, rather than treating LN configuration as a separate, easily forgotten step.

Infor LN Jobs Stuck in Active or Waiting: Fix the Job Daemon
Infor LN background jobs, reports, batch processes and print jobs, get stuck in Active or Waiting status when the job daemon on the enterprise server has stopped or lost its connection, or when a prior job crashed without releasing its status. Restart the job daemon and reset the stuck job's status through the Jobs session, and the queue resumes. A daemon that keeps stopping usually points to a memory, license or database connectivity problem on the server.
Error fixInfor LN bshell Process Stuck at 100% CPU: How to Diagnose and Fix It
A bshell process pinned at 100% CPU on the Infor LN application server almost always means one session is stuck in a 4GL loop, scanning an unindexed table, or waiting on a database lock. End the session from the Sessions Monitor first, then kill the OS process only if that fails, and check for a blocking database transaction before assuming it is a bug.
Error fixInfor LN Not Authorized to Run This Session: How to Fix It
Infor LN refuses to open a session with a not authorized message when the logged-in user's assigned role does not include that session, or when the session is blocked for the company they are logged into. Grant the session through Common > Authorization Management > Roles, or check the user's role and company context, and the session opens on retry. In most cases this is a permissions configuration issue, not a bug.
Error fixInfor LN DAL Out of Sync After a Custom Field: Cause and Fix
Infor LN throws a DAL, or table, out of sync error, or simply drops a new custom field silently, when a table's dictionary definition is changed but the generated DAL and dependent forms are not regenerated afterward. Running the standard sequence, table compile, DAL generation, then session/form compile, in Tools > Development after every dictionary change resolves it. Skipping any one of the three steps is what causes the mismatch.
AdvancedHow to extend business logic in Infor LN with DAL2
DAL2 lets you add custom validation, defaulting and calculation logic to Infor LN Enterprise Edition tables by writing a Java business logic handler class and registering it against a table event, without editing the standard DAL. Because the logic sits in your own package rather than inside Infor's base code, it survives upgrades that would otherwise overwrite a direct DAL change.
AdvancedHow to create a custom session in Infor LN Studio
Infor LN Studio's session designer generates a new maintenance, overview or detail session from a table definition, then lets you arrange fields, attach DAL2 validation, and wire menu access, all inside a custom package so the session survives upgrades. Building on a custom table gives the lowest upgrade risk; extending a standard table needs more care and re-testing after every release.
