Jobs will not print. The spooler crashes and event viewer shows error:
Faulting application name: spoolsv.exe, version: 6.1.7601.17777, time stamp: 0x4f35fc1d
Faulting module name: wsdapi.dll, version: 6.1.7601.17514, time stamp: 0x4ce7ca31
The wsdapi.dll is responsible for WSD Ports. We recommend to use only TCP/IP ports. However this issue also occurs when there is just a WSD port existent without really being in use.
ThinPrint Engine (any version)
Switch over to TCP/IP ports.
Delete the WSD ports by attaching a “dummy” printer to it and then delete the printer. This will cause the WSD port to also be deleted.
