GetPrinterDC()
查一下msdn里面有例子

[shenleav]

好像GetPrinterDC()是CPrintDialog类的成员函数,可是我想打印的时候不出现打印对话框...可以做到么?

用 API 试试:

'声明一串打印用 API
Private Declare Function OpenPrinter Lib "winspool.drv" Alias _
"OpenPrinterA" (ByVal pPrinterName As String, phPrinter As Long, _
ByVal pDefault As Long) As Long

Private Declare Function ClosePrinter Lib "winspool.drv" (ByVal _
hPrinter As Long) As Long

Private Declare Function StartPagePrinter Lib "winspool.drv" (ByVal _
hPrinter As Long) As Long

Private Declare Function EndPagePrinter Lib "winspool.drv" (ByVal _
hPrinter As Long) As Long

Private Declare Function StartDocPrinter Lib "winspool.drv" Alias _
"StartDocPrinterA" (ByVal hPrinter As Long, ByVal Level As Long, _
pDocInfo As DOCINFO) As Long

Private Declare Function EndDocPrinter Lib "winspool.drv" (ByVal _
hPrinter As Long) As Long

Private Declare Function WritePrinter Lib "winspool.drv" (ByVal _
hPrinter As Long, pBuf As Any, ByVal cdBuf As Long, _
pcWritten As Long) As Long

'定义一个新类型（打印用）
Private Type DOCINFO
pDocName As String
pOutputFile As String
pDatatype As String
End Type

'打印机句柄
Private mHdcPrn As Long

'打印机名称
Private mPrinterName As String
