Safe next steps
- For 3021 (ERROR_INVALID_PRINTER_DRIVER_MANIFEST), note whether the code came from a local printer, a network queue, or an application print request.
- Check the queue and connection, then compare the driver with the printer maker’s official package for the exact model.
- On shared office printers, ask the print-server administrator before clearing queues or changing drivers.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
