My background with VectorWorks is on the Mac platform. I have been experimenting a little with VW on Windows and am running into a problem. Items with a white fill print as all black, regardless of the printer driver selected and regardless of whether I have white or black VW background selected. I can work around this by creating a .pdf file from the Export menu and printing from that, but this adds a step to my workflow.
I am running VW 2015 SP5 on Windows 10. I had the same problem with Windows 7. Some printers/drivers used have been Bluebeam Revu (.pdf), HP T120 and Canon iR 2525
