The code below can be used to read the status of all printers, like in start-settings-printers.
You need to add System.Printing to the dotnet list of your project.

pclLps is LocalPrintServer dynamic
pclLps = new LocalPrintServer
pclEnu is IEnumerator dynamic
PcliEnumObject is PrintQueueCollection dynamic
PcliEnumObject = pclLps:GetPrintQueues()
pclEnu = PcliEnumObject:GetEnumerator()
bOK is boolean = pclEnu:MoveNext()
pq is PrintQueue dynamic
WHILE bOK
	pq = pclEnu:Current
	Trace(pq:FullName,pq:NumberOfJobs,pq:HasPaperProblem,pq:IsDoorOpened,pq:IsNotAvailable,pq:IsOffline,pq:IsInError,pq:IsPaperJammed,pq:IsOutOfPaper,pq:NeedUserIntervention,pq:IsTonerLow)
	bOK = pclEnu:MoveNext()
END

btw: in WD15 you can skip the IEnumerator steps and use FOR EACH directly
