Text is printed dark gray instead of black

[D-ominik]

When printing a document, the text is always printed in dark grey, regardless of the selected theme. When using a laser printer, this results in text that is unattractive and less legible.

I tried adding

@media print {
    body {
      background: white;
      color: black !important;
    }
}

to the theme CSS without any difference.

How can I achieve a text printed in black?
