用以下代码看看：（源自MSDN）
Example to Change Page Settings During a Print Job
Create a Standard EXE Project. Form1 is created by default.

Add a CommandButton to Form1, and paste the following code into the form's Declaration section:
Option Explicit

' Constants for Orientation.

' Constants for printer bin.

End Sub
Make sure that the printer orientation is set to Portrait and the paper source is set to Upper Tray or AutoSelect. Then run the Project and click on Command1.
If your printer has both an upper and a lower paper tray and supports both orientations, this will print the first page to the upper tray in Portrait and then a second page from the lower tray in Landscape.

上面的代码封装了一个函数：
Function ResetPrinterDC(PrinterName As String, hPrtDc As Long, _
PaperSource As Long, PaperOrient As Long) As Boolean

其中PaperSource 即为纸张来源

我先看看，感谢先

你的纸张来源和我的纸张来源意义不一样
你选择的是纸张型号来源比如A4
我要求的是自动，手动，牵引送纸

设置后就不要变了

[Tadpole0510]

Public Const DMBIN_MANUAL = 4
Public Const DMBIN_LOWER = 2
Public Const DMBIN_MIDDLE = 3
Public Const DMBIN_ONLYONE = 1
Public Const DMBIN_SMALLFMT = 9
Public Const DMBIN_TRACTOR = 8
其中 DMBIN_TRACTOR 是我需要的，
但是运行后打开 打印机－》属性－》常规－》打印首选项－》纸张/质量--纸张来源，
纸张来源设置还是没有变！！！

[Tadpole0510]

没有实现啊,怎么样才能解决?
