I am using QTextDocumentto generate html report and so far it works fine, now my report has multi sections witch is require each section on its own page, wrapping sections in table and then insert <div style=\"page-break-after:auto !important;\"></div> didn't work, as QTextDocumenthas limited support for html and css. also I did try to use QPaint, but this draws only the first page of my report.
Qt Code: 
  1. void SemesterResultsReport::printDivisionStudentsNotes() {
  2.     QMap<int, int> divisionsList = SemesterResultsReport::getSelectedDivisions();
  3.  
  4.     QPrinter *printer = new QPrinter(QPrinter::ScreenResolution);
  5.     printer->setFullPage(true);
  6.     printer->setResolution(90);
  7.     printer->setPaperSize(QPrinter::A4);
  8.     printer->setOrientation(QPrinter::Landscape);
  9.     printer->setPageMargins(5, 5, 5, 5, QPrinter::Millimeter);
  10.     /*printer->setOutputFormat(QPrinter::PdfFormat);
  11.     printer->setOutputFileName("sdf.pdf");*/
  12.  
  13.  
  14.     QPrintPreviewDialog *dlg = new QPrintPreviewDialog(printer, this);
  15.     connect(dlg, SIGNAL(paintRequested(QPrinter *)), this, SLOT(printOrder(QPrinter *)));
  16.     dlg->exec();
  17. }
  18.  
  19.  
  20. void SemesterResultsReport::printOrder(QPrinter *printer) {
  21.     QString strStream;
  22.     QTextStream out(&strStream);

  24.     QSqlQuery studentInfo, studentNotes;
  25.     QSqlRecord studentInfoRec, studentNotesRec;
