How Thunderbird prints

  • • A printed message starts with its subject, sender, date and recipients.
  • • Plain text messages print in a fixed width font.
  • • Pictures in the message print with it.

What that means when you compare two versions

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

What happens to the rest of the page

  • • The differences between the two files are highlighted.
  • • Useful before sending a revised draft.

Questions people ask

+Do I need both files?

Yes. Add the old and the new version to compare them.

+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 Thunderbird?

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