Edit the header in a Microsoft Print to PDF file

Change the running header on every page of a report or letter. PDFs made with Microsoft Print to PDF often have no real text, only drawn letter shapes. MythosPDF turns them back into text first, so this works on them too.

How to do it

  3. 3.Export PDF.

What that means when you edit the header

  • • Letters you type that already appear in the printout, in the same font, are copied from its own letter shapes, so they print identically.
  • • A letter the printout never used comes from the identified typeface. For fonts that are not openly available, MythosPDF asks before using the closest open font.
  • • After export, the recovered text can be selected, copied and searched, which the printout could not do.

How Microsoft Print to PDF writes the PDF

  • • Depending on the app and the fonts, Microsoft Print to PDF either embeds the fonts or draws every letter as a filled shape.
  • • When letters are drawn as shapes, the PDF has no text at all: you cannot select, copy or search anything on the page.
  • • Letters are placed one at a time in printer units, inside a flipped page transform.
  • • Thin letters such as l, i and I, and the dots of punctuation, are often collected from many lines into one shape drawn later.

How MythosPDF makes a Microsoft Print to PDF file editable

  • • The page is read with OCR, then every word is matched to the letter shapes that draw it.
  • • Letters are grouped into fonts by their outlines and size, so bold, regular and heading text stay apart.
  • • The typeface is identified from letter widths and shapes, and each line gets its real baseline.
  • • The page is rebuilt with text fonts made from the document's own letter outlines, so it looks exactly as printed.
  • • Every rebuilt letter is checked against the original position, and the page is compared pixel by pixel before you edit.

What happens to the rest of the page

  • • Headers keep their position and size.
  • • Each page's header is edited separately.

Questions people ask

+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.

+Will the page look different after recovery?

No. The rebuilt text uses the document's own letter outlines, and every page is compared with the original before you edit.

+Can I remove a header?

Yes. Delete its text on each page.
