Question

我为解决这个印刷问题而生气，我担心这个问题不完全符合这个社区的网络礼节，但我必须尝试。
我用MFC C ++编写了这个程序，它使用Window GDI在屏幕上生成一些自定义报告。 MSDN表示在OnPrint上使用正确的DPI重新计算进行绘制将为打印机准备好输出。很好，这就是我所做的，一切都适用于我的应用程序的几乎每个用户：

开发，UNICODE，Windows 7，每台打印机
发布，UNICODE，Windows 7，每台打印机
安装1，Windows XP SP3，每台打印机
安装2，Windows 7，每个打印机

但是第三次安装，使用Windows XP SP3，使用PDF Creator打印在纸上但不，打印出正确数量的页面但完全空白。
你知道我在哪里可以搜索问题吗？如果您需要代码段或我发布的任何其他内容。

请注意，m_VDStampa是GDI绘图的包装器，因此请按原样使用。
