下面是我打印一长图片的程序：m_pb 是一副bmp图片
CRect rect;
CPrintDialog dlg(FALSE);
if (dlg.DoModal() == IDCANCEL)
return;// dlg.GetDefaults();

// is a default printer set up?
HDC hdcPrinter = dlg.GetPrinterDC();
if (hdcPrinter == NULL)
{
MessageBox(_T("打印机忙!"));
}
else
{
// create a CDC and attach it to the default printer
CDC dcPrinter;
dcPrinter.Attach(hdcPrinter);

// call StartDoc() to begin printing
DOCINFO docinfo;
memset(&docinfo, 0, sizeof(docinfo));
docinfo.cbSize = sizeof(docinfo);
docinfo.lpszDocName = _T("client print");

// if it fails, complain and exit gracefully
if (dcPrinter.StartDoc(&docinfo) < 0)
{
MessageBox(_T("初始化错误!"));
}
else
{
// start a page

下面在打印图象的代码，打印缓冲区中的bmp图象，打印到纸的2/3大小。
// get the default printer
CRect rect;
