I was playing a little more with the tablet and the TPrintPreview Demo, I added an option to set the font and recreate the pages. I tryed many fonts and I got the same effect.
I saw the Tablet PC does not have typo of font “TrueType”,
I can see only “OpenType” and none scalable fonts.
I try to duplicate the problem using “wordpad” and the same font and the preview from “wordpad” is ok in both orientation modes.
I want you notice from the attachment in the first post:
The space between letters is the same but each letter has a smaller width.
