Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
PrintDocument1.Print()
End Sub
Private Sub PrintDocument1_PrintPage(sender As System.Object, e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
Dim stringFont As New Font("Arial", 16)
Dim rectDraw As New RectangleF(e.MarginBounds.Left, e.MarginBounds.Top, e.MarginBounds.Width, e.MarginBounds.Height)
Dim strFormat As New StringFormat
Dim s As String
s = "print word" '打印的内容
e.Graphics.DrawString(s, stringFont, Brushes.AliceBlue, rectDraw, strFormat)
End Sub
先拖过来控件PrintDocument1,然后双击PrintDocument1,在它的PrintPage事件中加入代码如下:
Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
dim a as String
a="abcd"
Dim mypen As Pen = New Pen(Color.Blue, 2)
e.Graphics.DrawString(a, New Font("宋体", 20), New Pen(Color.Black, 1).Brush, 30, 30)
End Sub
调用下面语句可直接用默认打印机打印出来:
PrintDocument1.Print()
txt文件:
procedure TForm1.Button1Click(Sender: TObject);
var
MyFile: TextFile;
SourceFile:TextFile;
Tmp:String;
begin
AssignPrn(MyFile);
AssignFile(SourceFile,'FilePath');
Reset(SourceFile);
Rewrite(MyFile);
Readln(SourceFile,Tmp);
While Not EOF(SourceFile) do
Begin
Writeln(MyFile, Tmp);
Readln(SourceFile,Tmp);
System.CloseFile(MyFile);
end;
图形文件需要TPrinter.canvas来打印了,
