    @mrjj Yes, i've tried using Verdana and works correctly

    I've modified my code like this:

    QFont bold("Verdana", 20);
    bold.setBold(true);
    painter.setFont(bold);
    painter.drawText(2000, 50, "BOLD TEXT");
    

    but no bold text..

    @TheCipo76
    Hi
    Tried your code.
    The QPainter was not active. ( logged errors to Creator)
    QPainter::begin(): Returned false
    QPainter::begin(): Returned false
    QPainter::setPen: Painter not active
    QPainter::setFont: Painter not active
    QPainter::setFont: Painter not active
    so font was never set, i think.
    if i do

    ....
          QPainter painter(&printer); // give it directly
           //painter.begin(&printer);
           QPen paintpen (Qt::black);
           painter.setPen(paintpen);
    ...
    

    i get
    alt text

      @mrjj i've made the changes you told me up but
      nothing changed
      no way to have bold text

      with qdebug i've checked font selection
      this is debug message

      Painter isActive: true
      Painter Font: QFont( "Verdana,20,-1,5,75,0,0,0,0,0" ) //Bold
      Painter Font: QFont( "Verdana,12,-1,5,50,0,0,0,0,0" )
      Painter Font: QFont( "Verdana,10,-1,5,50,0,0,0,0,0" )
      Painter Font: QFont( "Verdana,12,-1,5,75,0,0,0,0,0" ) //Bold
      Painter Font: QFont( "Verdana,11,-1,5,75,0,0,0,0,0" ) //Bold
      Painter Font: QFont( "Verdana,11,-1,5,50,0,0,0,0,0" )
      Painter Font: QFont( "Verdana,11,-1,5,75,0,0,0,0,0" ) //Bold
      Painter Font: QFont( "Verdana,11,-1,5,50,0,0,0,0,0" )

      75 is Bold ( as i've setted by code..)

      but was not applied

      Probably was a bug

                Sample is like 98% your code. just removed the Date stuff.
                Even to Image is your code, just to a pixmap.
                Rest of it, is the same. So something must have went wrong
                altering the code, or maybe it didnt use new code or something.

                    Good hunting. Now we know it will work so
                    its just to compare sample to actual code and see what could be difference.

                            Aha, and did you try the
                            http://doc.qt.io/qt-5/qtwidgets-richtext-textedit-example.html
                            example on mac too ?
                            We have other poster that has Bold issue on macOs.
                            https://forum.qt.io/topic/98726/qtextedit-make-text-bold

                            so its kinda important to know if RichText sample do not go bold for you either as it then
                            smells like a Qt thing /Xcode / macOS version thing.

                                  Hi
                                  (only talking macOs)
                                  So Rich Text can do bold but your code does not ?
                                  So unlike other poster - its sort of mixed.
                                  Very odd.
                                  Also if not even my sample with image give Bold text then
                                  something is not workings it should.
                                  I wonder if the font itself could be the issue.
                                  did you try with other fonts in the code ?

                                    Also if not even my sample with image give Bold text then
                                    something is not workings it should.
                                    I wonder if the font itself could be the issue.
                                    did you try with other fonts in the code ?

                                          Ok super , so i think its related.
                                          and what Qt are you using ?
                                          The other poster is using Qt 5.12.0
