Is the epub image a screenshot of the epub whilst on the PRST1? If so, what happens if you reduce the font-size using the buttons on the PRST1 and view the epub in landscape orientation, rather than portrait?
It looks to me as if all that is wrong is that the font-size is too big for each line to fit and the PRST1 is wrapping the overflow rather than letting it run off the right-hand edge. This is actually a good thing
as I'm not sure that earlier Sony models were able to wrap <pre> text. (
Just checked my PRS650, this model can also wrap <pre> text, perhaps it was the PRS505 which couldn't?)
I'll add a couple of PRST1 screenshot images shortly to illustrate my point. Photography is definitely not my strong suit
I don't think there's anything wrong with your calibre conversion settings. Having thought about it a bit more, having 'Smarten punctuation' UNCHECKED and 'Text justification' set to 'Left align' (or 'original') are probably a good idea for this type of file.
[Edit:] The following screenshots are taken from the same epub on the PRST1
- 1st: landscape orientation, best font-size, no line wrapping
- 2nd: landscape orientation, font-size too big, results in long <pre> lines wrapping
