打印小票

1,在Form中加入一个印刷的控件PrintDocument，取名为MyPrintDocument

2,新建一个一般类（不是窗体类），名叫MyPrinter，内容如下：

public class MyPrinter

{

private PrintDocument ThePrintDocument;

private Font titleFont;

private Font theFont;

private Color FontColor;

private float CurrentY;

static int PageNumber;

private int PageWidth;

private int PageHeight;

private int LeftMargin;

private int TopMargin;

private int RightMargin;

private int BottomMargin;

private ArrayList textList = new ArrayList();

private int currentIndex = 0;

public MyPrinter(PrintDocument _thePrintDocument, Font _theFont, Font _titleFont,Color _FontColor, ArrayList _textList)

{

ThePrintDocument = _thePrintDocument;

theFont = _theFont;

titleFont = _titleFont;

FontColor = _FontColor;

PageNumber = 0;

textList = _textList;

if (!ThePrintDocument.DefaultPageSettings.Landscape)

{

PageWidth = ThePrintDocument.DefaultPageSettings.PaperSize.Width;

PageHeight = ThePrintDocument.DefaultPageSettings.PaperSize.Height;

}

else

{

PageHeight = ThePrintDocument.DefaultPageSettings.PaperSize.Width;

PageWidth = ThePrintDocument.DefaultPageSettings.PaperSize.Height;

}

LeftMargin = ThePrintDocument.DefaultPageSettings.Margins.Left;

TopMargin = ThePrintDocument.DefaultPageSettings.Margins.Top;

RightMargin = ThePrintDocument.DefaultPageSettings.Margins.Right;

BottomMargin = ThePrintDocument.DefaultPageSettings.Margins.Bottom;

}

public bool DrawDocument(Graphics g)

{

try

{

DrawHeader(g);

bool bContinue = DrawItems(g);

g.Dispose();

return bContinue;

}

catch (Exception ex)

{

MessageBox.Show("失败" + ex.Message.ToString(), " - Error", MessageBoxButtons.OK, MessageBoxIcon.Error);

g.Dispose();

return false;

}

public void DrawHeader(Graphics g)

{

CurrentY = (float)TopMargin;

PageNumber++;

string PageString = "第" + PageNumber+"页";

StringFormat PageStringFormat = new StringFormat();

PageStringFormat.Trimming = StringTrimming.Word;

PageStringFormat.FormatFlags = StringFormatFlags.NoWrap | StringFormatFlags.LineLimit | StringFormatFlags.NoClip;

PageStringFormat.Alignment = StringAlignment.Far;

RectangleF PageStringRectangle = new RectangleF((float)LeftMargin, CurrentY, (float)PageWidth - (float)RightMargin - (float)LeftMargin, g.MeasureString(PageString, theFont).Height);

g.DrawString(PageString, theFont, new SolidBrush(Color.Black), PageStringRectangle, PageStringFormat);

CurrentY += g.MeasureString(PageString, theFont).Height;

StringFormat TitleFormat = new StringFormat();

TitleFormat.Trimming = StringTrimming.Word;

TitleFormat.FormatFlags = StringFormatFlags.NoWrap | StringFormatFlags.LineLimit | StringFormatFlags.NoClip;

TitleFormat.Alignment = StringAlignment.Center;

RectangleF TitleRectangle = new RectangleF((float)LeftMargin, CurrentY, (float)PageWidth - (float)RightMargin - (float)LeftMargin, g.MeasureString("收费单", titleFont).Height);

g.DrawString("收费单",titleFont,new SolidBrush(FontColor),TitleRectangle,TitleFormat);

CurrentY +=g.MeasureString("收费单",titleFont).Height;

}

public bool DrawItems(Graphics g)

{

StringFormat TextFormat = new StringFormat();

TextFormat.Trimming = StringTrimming.Word;

TextFormat.FormatFlags = StringFormatFlags.NoWrap | StringFormatFlags.LineLimit | StringFormatFlags.NoClip;

TextFormat.Alignment = StringAlignment.Near;

for (int i = currentIndex; i < textList.Count; i++)

{

string var = textList[i].ToString();

RectangleF TextRectangle = new RectangleF((float)LeftMargin, CurrentY, (float)PageWidth - (float)RightMargin - (float)LeftMargin, g.MeasureString("收费单", titleFont).Height);

g.DrawString(var, theFont, new SolidBrush(FontColor), TextRectangle, TextFormat);

CurrentY = CurrentY + g.MeasureString(var, theFont).Height;

if ((int)CurrentY > (PageHeight - TopMargin - BottomMargin))

{

currentIndex = i+1;

return true;

}

return false;

}

3，回到原来的Form中，给MyPrintDocument添加PrintPage事件

private void MyPrintDocument_PrintPage(object sender, PrintPageEventArgs e)

{

bool hasNextPage = mp.DrawDocument(e.Graphics);

if (hasNextPage)

{

e.HasMorePages = true;

}

4，撰写打印机设置对话框函数

private bool SetupThePrinting()

{

PrintDialog MyPrintDialog = new PrintDialog();

MyPrintDialog.AllowCurrentPage = false;

MyPrintDialog.AllowPrintToFile = false;

MyPrintDialog.AllowSelection = false;

MyPrintDialog.AllowSomePages = false;

MyPrintDialog.PrintToFile = false;

MyPrintDialog.ShowHelp = false;

MyPrintDialog.ShowNetwork = false;

if (MyPrintDialog.ShowDialog() != DialogResult.OK)

return false;

MyPrintDocument.DocumentName = "收费单 ";

MyPrintDocument.PrinterSettings = MyPrintDialog.PrinterSettings;

MyPrintDocument.DefaultPageSettings = MyPrintDialog.PrinterSettings.DefaultPageSettings;

MyPrintDocument.DefaultPageSettings.Margins = new Margins(100, 40, 100, 40);

ArrayList textList = new ArrayList();

mp = new MyPrinter(MyPrintDocument, new Font("Tahoma", 8, FontStyle.Regular, GraphicsUnit.Point), new Font(FontFamily.GenericSerif, 18, FontStyle.Bold, GraphicsUnit.Point), Color.Black, textList);

return true;

}

5，最后加上打印按钮，打印预览按钮的单击事件

1），打印按钮的单击事件

private void btnPrint_Click(object sender, EventArgs e)

{

if (SetupThePrinting())

MyPrintDocument.Print();

}

2）打印预览按钮的单击事件（根据需要）

private void btnPrintPreview_Click(object sender, EventArgs e)

{

if (SetupThePrinting())

{

PrintPreviewDialog MyPrintPreviewDialog = new PrintPreviewDialog();

MyPrintPreviewDialog.Document = MyPrintDocument;

MyPrintPreviewDialog.ShowDialog();

}

6，现在你或许要问，那我的打印数据如何加入呢？其实就在刚才写的打印机设置对话框函数里面，如下：

ArrayList textList = new ArrayList();

//textList.Add("收费单");

//textList.Add("2009-04-01");

//textList.Add("开始时间：12:00 ");

//textList.Add("结束时间：13:00 ");

//textList.Add("时间单位：4 ");

//textList.Add("单位时间价格：20.00元 ");

//textList.Add("消费价格：80.00元 ");

//textList.Add("------------------------------------------------------------- ");

//textList.Add("2009-04-01 ");

//textList.Add("开始时间：12:20 ");

//textList.Add("时间单位：3 ");

//textList.Add("单位时间价格：20.00元 ");

//textList.Add("消费金额：60.00元 ");

//textList.Add("------------------------------------------------------------- ");

//textList.Add("合计：140.00元 ");

//textList.Add("2");

mp = new MyPrinter(MyPrintDocument, new Font("Tahoma", 8, FontStyle.Regular, GraphicsUnit.Point), new Font(FontFamily.GenericSerif, 18, FontStyle.Bold, GraphicsUnit.Point), Color.Black, textList);

return true;

也就是，你只要自己根据你现有的数据将信息一行一行Add到textList中，就可以了

楼上的，1万行你复制一万行？for循环留着干嘛的啊？个人觉得不一定现成的东西都是对自己最有利的。

付参考效果图。
