我无法设置 PosPritnter 类的属性。例如 PageModeStation、PageModeVerticalPosition、PageModePrintArea 等。
PosPrinter posPrinter = (PosPrinter)posExplorer.CreateInstance(posPrinterInfo);
posPrinter.Open();
posPrinter.Claim(1000);
posPrinter.DeviceEnabled = true;
posPrinter.PageModeVerticalPosition = 10; //<--- Exception thrown: Failed to set property PageModeVerticalPosition
异常详情:
Microsoft.PointOfService.PosControlException was unhandled
Message="Failed to set property PageModeVerticalPosition."
Source="Microsoft.PointOfService"
ErrorCodeExtended=0
StackTrace:
at Microsoft.PointOfService.Legacy.LegacyProxy.SetProperty(String propertyName, Object propertyValue)
at Microsoft.PointOfService.Legacy.LegacyPosPrinter.set_PageModeVerticalPosition(Int32 value)
....
有什么建议么?
