因此，如果您将PDF打印机设置为默认打印机，则可以使用。 我认为这不是完美的解决方案，但至少是一种解决方法。

 SAPbobsCOM.CompanyService oCmpSrv;
        SAPbobsCOM.ReportLayoutsService oReportLayoutService;
        SAPbobsCOM.ReportLayoutPrintParams oPrintParam;
        oCmpSrv = oCompany.GetCompanyService（）;
        oReportLayoutService =（ReportLayoutsService）oCmpSrv.GetBusinessService（SAPbobsCOM.ServiceTypes.ReportLayoutsService）;
        oPrintParam =（ReportLayoutPrintParams）oReportLayoutService.GetDataInterface（SAPbobsCOM.ReportLayoutsServiceDataInterfaces.rlsdiReportLayoutPrintParams）;
        oPrintParam.LayoutCode =" INV20014";
        oPrintParam.DocEntry = 350;
        oReportLayoutService.Print（oPrintParam）;
