Saving as PDF issues

Hi Brian,
I’ve attached/uploaded the 3DM file, along with a screen grab and some PDFs. I’ve set the print settings in Rhino to Scaled to fit and using the Window to create a centred print-out. Initially, I set the print settings to the Raster setting, and Saved as PDF which gave me a PDF the same as the preview. I then changed the settings to Vector and again saved as a PDF and this time the PDF is aligned to the the top left corner, despite being central in the Print Preview window.
Hope you can help.
Thanks,
