Restarted the print spooler and removed paused jobs.

A safe way to narrow this down is to change one variable at a time.

Likely cause: The printer received a new IP while Windows still uses the old standard TCP/IP port.

What I would try: Reserve the printer address in DHCP, update or recreate the TCP/IP port and avoid WSD discovery for a fixed office printer.

If this is a production system, test the change during a maintenance window.

Incident analysis

Updated 4w ago• Trouble ID

Most likely causes

The printer received a new IP while Windows still uses the old standard TCP/IP port. 84%
A recent software, firmware or configuration change is exposing an existing compatibility issue. 38%

Summary

The reported behaviour is consistent with the printer received a new IP while Windows still uses the old standard TCP/IP port. The safest next step is to verify that hypothesis with a reversible test before making permanent configuration changes.

Suggested Fixes

Verify the likely cause
Reserve the printer address in DHCP, update or recreate the TCP/IP port and avoid WSD discovery for a fixed office printer.
Validate and monitor
Reproduce the issue once after the change, review relevant logs or metrics, and keep a rollback path until the system has remained stable.
