Blank or missing pages in QPrintPreviewDialog

Project with sample code attached.
issue 1:
1) Build project
2) run app and click on 'using QTextEdit.print()' button
result: Print preview will open with just the second page showing
expected: Print preview of both pages

issue 2:
1) Build project
2) run app and click on 'using QPainter' button
result: Print preview with two blank pages
expected: Print preview of both pages

work around: comment out ui->textEdit->hide() call in MainWindow constructer and uncomment the call in 'on_pushButton_2_clicked(). This time the two pages will show as expected
