Quick PDF Library and GetPageText(1) is not really designed for TXT extraction in the way that you are expecting it. We have made major changes to the TXT extraction in 7.24 and 7.25 versions. We plan to add a full TXT file extraction to one of the early releases of QPL version 8.

Here is some sample output from your sample1.pdf. Let me know if this is what you are expecting.

You will need to copy and paste the text above into something like notepad that uses a fixed width font. The font used in the message above is proportional which makes it look like the text alignment is not correct.
