Hello again!
I’m having a strange issue when printing: when I print (to various printers including PDF), my file suddenly does not show the viewports (vital to the drawings). I’m not sure why, as they were working just yesterday. 
Here is an image to show what I’m talking about. I tried printing to PDF anyway to see if it was just a preview error, but indeed the PDF did not have any of the viewports in the drawing.
Any ideas?
Reboot does not help, nor does DPI seem to have any influence (as was the case in similar thread).
I will also note that the viewports are in a modified 'Arctic" display mode with individual elements having different display modes. Switching viewport display mode does not seem to improve the situation EXCEPT when switching to wireframe, in which case the viewport suddently becomes visible.
Okay, so I’ve managed to get the viewports to appear again, but only when I turn off shadows for Arctic under Display Modes in Options. Does anyone have ideas as to why that is? It would be nice to keep the shadows on, and I’m not sure I’ve ever had an issue with that before.
This could be a display driver issue.
Run the Rhino SystemInfo command and please post the results.
Try the output in raster mode.

Here’s the current driver from earlier this month:
https://www.nvidia.com/Download/driverResults.aspx/156780/en-us
Choose the Advanced option and select a “Clean” install.
Any better?
@John_Brock
I’ve updated the driver as per your suggestion, but unfortunately it hasn’t changed anything.
