How to create an instance

Question

Hi all,
Actually, I want to create an instance without priting or sending to any destination.
My code steps should be:
1. logon
2. get report object
3. set parameters information
4. create an instance / schedule report
once I create all instances for different reports, then I need to read all created instance objects (report with data populated) and sent to printer.
Is this possible? If possible, please suggest how to proceed further.
Thanks,
Krishna

here is a general code sample - you may need to modify it.
<%
IEnterpriseSession oEnterpriseSession = null;
IInfoStore oInfoStore = null;
String username = "administrator";
String password = "<password>";
String cmsname = "<cmsname>";
String authType = "secEnterprise";
String reportName = "<reportname>";
     oEnterpriseSession = CrystalEnterprise.getSessionMgr().logon(username, password, cmsname, authType);
     oInfoStore = (IInfoStore)oEnterpriseSession.getService("","InfoStore");
     String query =      "select top 1 * from ci_infoobjects where si_name='" + reportName + "' and si_instance=0";
     IInfoObjects reports = oInfoStore.query(query);
     IReport report = (IReport) reports.get(0);
     ISchedulingInfo schedInfo = report.getSchedulingInfo();
     schedInfo.setRightNow(true);
     schedInfo.setType(CeScheduleType.ONCE);
     // schedule the report to default destination.
     oInfoStore.schedule(reports);
     // retrieve report instance. You may have do this multiple times if the report is still in process.
     query = "select top 1 * from ci_infoobjects where si_name='" + reportName + "' and si_instance=1 order by si_creation_time desc";
     IInfoObjects instances = oInfoStore.query(query);
     IInfoObject instance = (IInfoObject) instance.get(0);
     IReportAppFactory rptAppFactory = (IReportAppFactory)es.getService("", "RASReportService");
     ReportClientDocument clientDoc = rptAppFactory.openDocument(instance, 0, Locale.ENGLISH);
     //set PrintReportOptions object properties. Look in RAS SDK documentation for further info.
     clientDoc.getPrintOutputController().printReport(PrintReportOptions object);
     clientDoc.close();
oEnterpriseSession.logoff();
