如何设置打印机DPI

[sun28long]

PrinterSettings ps = new PrinterSettings();
ps.DefaultPageSettings.PrinterResolution.X = 96;
ps.DefaultPageSettings.PrinterResolution.Y = 96;
ps.PrinterName = PrinterName;
prtDocument.DefaultPageSettings.PrinterSettings = ps;

/////////////////////////////////////////////////////////////////////////
其中ps.DefaultPageSettings.PrinterResolution.X = 96;
ps.DefaultPageSettings.PrinterResolution.Y = 96;
设置无效，X,Y dpi认为原来的600；但是编译时没报PrinterResolution.X,Y是只读.
如何设置打印机dpi？可以设成96吗？

俺也正在搞这个，只是你这个俺是知道的，你必需得设置为自定义DPI，然后才会使你的设置生效：

PrinterSettings ps = new PrinterSettings();
ps.DefaultPageSettings.PrinterResolution.X = 96;
ps.DefaultPageSettings.PrinterResolution.Y = 96;
//使用自定义DPI
ps.DefaultPageSettings.PrinterResolution.Kind = PrinterResolutionKind.Custom;

ps.PrinterName = PrinterName;
prtDocument.DefaultPageSettings.PrinterSettings = ps;
