Question

我正在开发一个程序来管理库存并通过Qt进行销售，我正在尝试打印销售收据，但仅从几乎一半的纸张开始打印

    settings.beginGroup("Geral");
    QString nomeEmpresa = settings.value("nomeEmpresa").toString();
    QString cnpj = settings.value("cnpj").toString();
    settings.endGroup();

    QString content = "<b>" + nomeEmpresa + "</b><br/>" + cnpj + "<br/>"
                      "<br/><hr style='border: 1px solid #000000;'/>"
                      "<br/><table><thead><tr><th>Quantidade</th><th>Produto</th></tr></thead>"
                      "<tbody>";

    for(int i = 0; i < items.size(); i++){
        content.append("<tr><td>" + QString::number(items.value(i).quantidade) + "</td><td>" + items.value(i).produto.codigoVenda() + "</td></tr>");
    }

    content.append("</tbody></table><br/><br/><br/><b>Obrigado pela preferência. Volte sempre</b>");

    //QString content = "Teste de alinhamento da impressao";

    QTextDocument doc;
    doc.setHtml(content);

    QPrinter printer;
    printer.setResolution(QPrinter::HighResolution);
    printer.setOutputFormat(QPrinter::NativeFormat);
    printer.setOrientation(QPrinter::Portrait);

    QPrintDialog dlgImpressao(&printer);
    if(dlgImpressao.exec() == QPrintDialog::Accepted){
        doc.print(&printer);
    }

左侧是我所在城市的超级市场的收据，右侧是正在打印的收据Qt

我希望它的打印方式与左侧示例相同，但没有任何进展

QPrinter打印与Qt不对齐
