Spooler
Definition
The Windows service that queues and coordinates print jobs.
Detailed explanation
The Spooler is the Windows service that accepts print jobs, stores job data, and coordinates print processors, drivers, port monitors, and printers. Vendor modules can load into the shared spooler process, so one faulty component can affect multiple queues. SPL and SHD files represent queued content and metadata. The v3 driver model permits vendor rendering DLLs, print processors, and port monitors inside the pipeline, whereas newer v4 and IPP approaches rely more heavily on standardized components. A repeated crash on one queued job can therefore originate in data conversion rather than printer connectivity.
