Hello all. My first post here. I am having a devil of a time with something that ought to be simple.

I am trying to generate a simple text Report. It is one page only. I build and format the Report using HTML from the "Supported HTML Subset". I offer a "Save Report to PDF" Button, and a "Print Report" Button. I have played with font families, font sizes, styles, colors, etc. All the HTML codes that I have tried are working perfectly except for horizontal alignment in the Print-out. The PDF file is properly aligned, as verified by Acrobat Reader.

I have pulled my hair out for a week trying various things, eating up a few hundred sheets of paper, trying to get the print-out to align. I humbly challenge someone to please provide the trick that makes the Print-out align properly.

As shown in the overly-simplified, yet complete and compilable code below, I assign the HTML codes to a QString as demonstrated in many different examples throughout the web. The posted code demonstrates the problem. The PDF file is correct, the Print output is not.

Since all other HTML Tags and Properities are working (I haven't included all of them in the simplified code), it appears to me that the "align=center" issue must have a trick to it, but if so, I think I would have found reference on the web to it. I have tried many other methods, all to no avail, which is why I would like to challenge others to see if they get the same result. Please indicate what I'm doing wrong, or leaving out a step.

I am using Qt 5.2.0, Qt Creator 3.0.0, Windows 7 Pro 64bit, and the MSVC2010 32-bit Debug Kit.

Thank You for your help.
