我正在尝试使用printdocument从数据库中打印数据，但我将其打印到指定范围内的数据打印位置，但是仍然有2处出错

仍然无法按预期工作的事情是

• 在打印时，如果页面几乎被完全使用，则会添加空白页，并且只打印页眉
• 如果页面已满，则下一页将再次从范围的第一项开始（通过使用多个列表进行固定，因为我无法弄清楚如何创建带有子列表的列表）

这是我必须调用printdocument的代码

private void button3_Click(object sender, EventArgs e)//print
{
    range();
    try
    {
        if (artikel == true)
        {
            itemperpage = totalnumber = 0;
            printPreviewDialog1.Document = printDocument1;
            print = true;
            printDocument1.Print();
            // this.Close();
        }
    }
    catch (Exception q) { MessageBox.Show("" + q); }
}

这是printdocument的代码

private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
    if (artikel == true)
    {
        Font messageFont = new Font("Arial", 14, System.Drawing.GraphicsUnit.Point);

        float currentY = 10;// declare  one variable for height measurement 
        e.Graphics.DrawString("                                                                                                                  I N K O O P A R T I K E L E N ", DefaultFont, Brushes.Black, 10, currentY);//this will print one heading/title in every page of the document 
        currentY += 15;
