Map Pedometer - How far did you go?

Tried printing to pdf, update printer software etc., these made no difference.
Found an option before printing to 'let the printer choose the colors' and it finally printed out in a sort of rosy color.
Maybe a default darker / generic color for the elevation profile may help.
Thanks for your help.

Yes I am using the print page you listed.
I am using a Chrome browser Version 67.0.3396.99 (Official Build) (64-bit).
Everything around the elevation profile prints except the elevation line gain/loss.
Thank you

Elevation profile does not print.
The graph prints but Not the elevation profile line.
Tried 'prt scrn' into windows 'paint' but that didn't work either.
