I think you should install the very latest version of microstation as something is very wrong with your printing as I said I used your file and your pentable in my version of microstation ss2 and in ss1 and both worked fine but I did not use the printer.pltcfg but the pdf.pltcfg instead I think your printer.pltcfg file has some settings that have been changed and your windows pdf maker doesnt like it .. especially the part of making rounded or mitered corners...
What happens if you print straight to paper with your pentable and a windows configured system printer...?
