I am pretty baffled at this point. I successfully can add my shared local windows printer to my macbook pro running El Capitan but when I go to print the jobs just hang and never leave the queue. It's a Laserjet 4100 and I have tried both the PCL and postscript drive to no avail. I can print to the shared printer using a Win7 laptop and I can also ping my windows 10 box from the Mac. Is there something I am missing within the Mac OS? TIA.
