The issue is:

text-shadow: none in *::first-line from the @media print-section 

So in (we're using child theme of Boost but would presumably work in Boost parent).

Alter: 

\theme\boost\scss\bootstrap\_print.scss

and remove *::first-line i.e. change:

@if $enable-print-styles {
  @media print {
    *,
    *::before,
    *::after,
    *::first-letter,
    *::first-line {
      // Bootstrap specific; comment out `color` and `background`
      //color: #000 !important; // Black prints faster:
                                //   http://www.sanbeiji.com/archives/953
      text-shadow: none !important;
      //background: transparent !important;
      box-shadow: none !important;
    }

to

@if $enable-print-styles {
  @media print {
    *,
    *::before,
    *::after,
    *::first-letter
     {
      // Bootstrap specific; comment out `color` and `background`
      //color: #000 !important; // Black prints faster:
                                //   http://www.sanbeiji.com/archives/953
      text-shadow: none !important;
      //background: transparent !important;
      box-shadow: none !important;
    }
