C# 实现简单打印的实例代码

主窗体代码如下:

            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

        }

        void printDoc_PrintPage(object sender, PrintPageEventArgs e)
        {
            string line = null;
            //设置一页的行数=打印区域的高度除以字体高度.
            float pageLine = e.MarginBounds.Height / printFont.GetHeight(e.Graphics);
            //循环打印每一行
            for (int count = 0; count < pageLine && ((line=sr.ReadLine())!=null); count++)
            {
                float singleLine=e.MarginBounds.Top+(count*printFont.GetHeight(e.Graphics));
                e.Graphics.DrawString(line, printFont, Brushes.Black, e.MarginBounds.Left, singleLine);
            }
            //判断是否继续打印
            if (line != null)
                e.HasMorePages = true;
            else
                e.HasMorePages = false;

        }
    }
</div>
