系统绘图；e.HasMorePages问题

我花了几天时间试图解决C#中的这个大问题：我正在尝试打印21篇文章（账单）票证格式，但纸卷有限制，占用了几页的分隔打印，但我无法从一页跳到打印文章#17，并用#18继续到另一页，请帮助。。

            int numberitems = items.Count; //21
            //numberitems / linespage = 1.23 = 2 Pages True :)
            if (linesprinted <= linesperpage)
            {
                linesprinted++;
                e.HasMorePages = false;
            }
            else {
