Okular - Printing bug?

I tried to replicate your scenario, and it seems there’s a problem with that PDF virtual printer.

I compiled a simple .tex using PdfLateX compiler:

\documentclass{article}

\usepackage{lettrine}
\usepackage{GoudyIn}
\renewcommand{\LettrineFontHook}{\GoudyInfamily{}}
\begin{document}
	\Huge \lettrine{H}{ello world}
\end{document}

Then I got the output PDF with subset of the font embedded:

Then I printed that file using the PDF virtual printer:

So the embedded subset of font was removed, and now it’s substituted by a random font.

If I download Goudy Initialen Font and put it in ~/.local/share/fonts/GoudyInitialen folder then run fc-cache -fv, that file will correctly render
