QPainter bug or QPrinter bug?

I think the general problem is that you don't into account that the screen and the pdf have different resolutions. I've been printing using Qt's PDF generator and I can assure you it works just fine.

As for the image, I'd say the Mono format gets stored as an image that doesn't support transparency (JPG maybe?) or it gets converted to such a format. Just to be sure it's not the problem with the pdf renderer in kpdf, check the file with some other viewer (okular or acroread).

I have been trying in many different machines with different kernels. In Windows, I tried CutePDF writer (http://www.cutepdf.com/), as well as Adobe's pdf writer. In linux, I have tested on Fedora core 4 and core 10, as well as enterprise Linux 4.0. For pdf viewer, I have tried acrobat in windows. In Linux, I tried kpdf, evince, and okular. All of them give the same error result.

However, if I switch to QImage::Format_Indexed8, it works fine. But QImage::Format_Indexed8 is really a waste of resources. All I need is two colors in the image...

I don't know why the font is distorted by painter...

I just reported this bug to Cattell a few weeks ago:
