同一程序在不同打印机下的图片打印问题～～～～～

[bigant888]

我得打印程序，在联想喷墨打印机上打印文本＋图片正常，看在HP得激光打印机上打印就只能打印文本，无法输出图片！用IE在HP上打印图片可以！哪位大哥帮帮忙，看看是什么问题！
另：求打印编程详细资料！
谢谢！

从你提供的两个网址中，下载了一个CPAGE的打印类，它可以正确的输出图片到激光打印机。它用的是下面的两个打印函数！
BOOL WINAPI PrintTheBitMap(PRTTYPE *ps)
{
BITMAPINFOHEADER bi;
RECT Rect;
if(InitDIB(ps)==FALSE)
return FALSE;
DibInfo(hbiCurrent, &bi);

if (!IsRectEmpty(&rcClip))
{
bi.biWidth = rcClip.right - rcClip.left;
bi.biHeight = rcClip.bottom - rcClip.top;
}
/* Fix bounding rectangle for the picture .. */

Rect.top = ps->rc.top;
Rect.left = ps->rc.left;
Rect.bottom = ps->rc.bottom-ps->rc.top;
Rect.right = ps->rc.right-ps->rc.left;
ps->rc.right=Rect.right;
ps->rc.bottom=Rect.bottom;
/* ... and inform the driver */
ps->pDC->Escape(SET_BOUNDS, sizeof(RECT), (LPSTR)&Rect, NULL);
PrintDIB(ps, ps->rc.left, ps->rc.top, ps->rc.right, ps->rc.bottom);
FreeDib();
return TRUE;
}
void WINAPI PrintDIB (PRTTYPE *ps, int x, int y, int dx, int dy)
{
BITMAPINFOHEADER bi;
int dibX, dibY;
int dibDX, dibDY;

if (!bLegitDraw)
return;

DibInfo (hbiCurrent, &bi);

if (IsRectEmpty (&rcClip)){
dibX = 0;
dibY = 0;
dibDX = (int)bi.biWidth;
dibDY = (int)bi.biHeight;
}
else{
dibX = rcClip.left;
dibY = (int)bi.biHeight - 1 - rcClip.bottom;
dibDX = rcClip.right - rcClip.left;
dibDY = rcClip.bottom - rcClip.top;
}

if (hdibCurrent){
/* Stretch the DIB to printer DC */
StretchDibBlt ( ps->pDC->GetSafeHdc(),
x,
y,
dx,
dy,
hdibCurrent,
dibX,
dibY,
dibDX,
dibDY,
SRCCOPY);
}

不知道为什么程序中用StretchBlt不能正确送到激光打印机打印，而可以送到喷墨打印机中。
为什么？学习中...........

春节回来，顶一下！
我用CVIEW做打印预览测试时，可以正常显示但是在问题也是在激光打印机无法打印图片！
下面是我的打印代码：请哪位大哥帮我看看！

建议试一试升级激光打印机的驱动

我感觉跟驱动关系不是很大,因为如果驱动有问题,那么IE应该也不对，我感觉是不是在处理DC的时候的问题，我是猜得，参考一下，很有可能不对
