Microsoft recently pushed out updates that break LPR/LPD (the ability to get print jobs from Unix/Linux and iSeries). Currently unless something has changed in the past 2 weeks, the only solution is to roll back the updates. Microsoft has also been threatening to deprecate (eliminate) LPR/LPD from Windows Server since 2012. Not sure what would replace it to allow print functionality between server types.
