由于16.0.2版本中的document.Print()执行后打印很慢至少需要等待10秒，所以把版本升级到了16.4.1，升级后本来正常的标签自动变成了横向的，并且PrinterSettings里的相关设置也无效。项目是WPF+ActiveReport，使用的静默打印。标签只是显示几个string，一个二维码，没有其它复杂的东西，然后每次执行完document.Print()后，至少还要等待很长时间。具体代码如下：
//静默打印
PageReport pageReport = new PageReport(new FileInfo(strFileName));
PageDocument document = new PageDocument(pageReport);
//加载数据
if (aryParams != null && aryParams.Length > 0)
{
for (int i = 0; i < aryParams.Length; i++)
{
pageReport.Report.ReportParameters.DefaultValue.Values.Add(aryParams);
}
}
//设置打印机
PrinterSettings settings = new PrinterSettings();
settings.ShowPrintDialog = false;
settings.ShowPrintProgressDialog = false;
settings.Printer.DefaultPageSettings.Margins.Bottom = 0;
settings.Printer.DefaultPageSettings.Margins.Left = 0;
settings.Printer.DefaultPageSettings.Margins.Right = 0;
settings.Printer.DefaultPageSettings.Margins.Top = 0;
settings.Printer.PaperSize.RawKind = 0;
settings.UsePrintingThread = true;
//宽高换算成inch 然后再乘以100
var dWidth = pageWidth * 0.3937m * 100;
var dHeight = pageHeight * 0.3937m * 100;
settings.Printer.PaperSize.Width = Convert.ToInt32(dWidth);
settings.Printer.PaperSize.Height = Convert.ToInt32(dHeight);
settings.Printer.PrinterName = strPrinterName;
//DateTime dtStart = DateTime.Now;
for (int i = 0; i < iCopies; i++)
{
document.Print(settings);
//PrintExtension.Print(document, settings);
}
