分享VB。NET中GetDeviceCaps（）API函数如果调用

我当然看过，但大哥，用PrintDocument.DefaultPageSettings.Margins 计算边距，实际上打印得到的效果是Margins+打印机的缺省边距，不信你打一页用尺子量一量，不过你提供的方法是可以在设定边距大于打印机缺省边距，不给用户预先提示的情况下设定边距，如果用户设定边距过小时要给出提示，就无法达到目的。

have you looked into
PrintDocument.DefaultPageSettings.Margins
?
Declare Function GetDeviceCaps Lib "gdi32.dll" (ByVal hDc As IntPtr,
ByVal funct As Integer) As Integer
in OnPrintPage, its parameter PrintPageEventArgs has a Graphics property which has a GetHdc method which will give you the handle:
e.Graphics.GetHdc()
