How Firefox prints

  • • Firefox adds the page title, web address, page number and date by default.
  • • Simplified reading view prints articles in a clean single column.
  • • Windows fonts and web fonts print side by side.

What that means when you add a watermark

  • • Page tools work on the printout as it is; no text recovery is needed.

What happens to the rest of the page

  • • The watermark is added as a layer; the original page content is not rewritten.
  • • Works on every page at once.

Questions people ask

+Can I remove a watermark later?

Keep the original file. Watermarks are added to the copy you download.

+Why can't I select text in my Microsoft Print to PDF file?

The driver often draws every letter as a shape instead of writing text. MythosPDF reads those shapes and turns them back into real text before you edit.

+Is it better to reprint from Firefox?

If you still have the Firefox file and a lot to change, yes. For a quick fix to the PDF you already have, editing it is faster.
