这是我用来制作图像的代码。
Bitmap bitmap;
bitmap.CreateBitmap(715, 844,1,1, NULL);
CDC memDC;
memDC.CreateCompatibleDC(NULL);
memDC.SelectObject(&bitmap);
CString SS="Sun Goes Down";
memDC.TextOutA(1,2,SS);
CImage image;
image.Attach(bitmap);
image.Save(_T("C:\test.bmp"), Gdiplus::ImageFormatJPEG);

一切都好，现在我只想将该图像发送到打印...

我用
DWORD pcchBuffer=100;
char * pszBuffer=new char[100];
GetDefaultPrinter(pszBuffer,&pcchBuffer);
again all is ok.
再次一切正常。

要获得默认的打印机名称，对于打印，我知道 WritePrinter 函数，但是该函数为参数 LPVOID 提供了打印缓冲区，我如何发送图像进行打印？非常感谢！

Instead of making the image, saving it, then printing it, you should:
而不是制作图像，保存，然后打印它，您应该：
- Create a DC for the printer (see http://msdn.microsoft.com/en-us/library/dd183521%28VS.85%29.aspx)
- Paint the image on this DC
- Write or paint whatever you want on the DC
- Close the DC
- 为打印机创建 DC（请参阅http://msdn.microsoft.com/en-us/library/dd183521%28VS.85%29.aspx）
- 在此 DC 上绘制图像
- 在 DC 上随心所欲地书写或绘画
- 关闭 DC
Look for all the detailed steps on MSDN.
在 MSDN 上查找所有详细步骤。
