convert 2 PDF nearly perfect, but ...

... theres just one little detail:

The converted PDFs are nearly perfect to be read on my txtr beagle but they have on each page at the lower end one line of free space as seen in the following pic marked in red:



I have no idea how this line can be used to have one more line of text?

Do you have any suggestions how this could be configured? :blink:

Thanks in advance
