the output PDF is A4 ratio, I need a 4:3 ratio which fit page to full screen. I think wkhtmltopdf have some option, or some print control css can control this, but I don't know how.
The default page size of the rendered document is A4, but using the --page-size option this can be changed to almost anything else, such as: A3, Letter and Legal. For a full list of supported pages sizes please see http://doc.trolltech.com/4.6/qprinter.html#PageSize-enum.
For a more fine grained control over the page size the --page-height and --page-width options may be used
--page-height <unitreal> Page height (default unit millimeter) --page-size <size> Set paper size to: A4, Letter, etc. --page-width <unitreal> Page width (default unit millimeter)
