Report does not print exactly same as it appears at design time

Question

Hello,
I am using SAP Crystal report with VS 2010.
I designed a report. At design time every thing appears fine. Margins are set to 0, printer is selected and page size is custom.(right click on report, design>pagesetup)
When I use <reportname>.printtoprinter(), it dramatically changes the text size and margins of the report in hard copy. I tried literally everything for this. Especially It adds nearly 2 inches extra margin at top.Also , at run time it changes the font size to 8 or 9 points if i have set it to 12 at design time.
I get the same problem if I do following:
  crystalReportViewer1.ReportSource = rptRcAbh;
   crystalReportViewer1.PrintReport();
HOWEVER!!
When I do this:
  crystalReportViewer1.ReportSource = rptRcAbh;
AND when I manually click the print button of crystal report viewer, i get EXACTLY SAME result as design time. This is what I am expecting from printoprinter() method. But Its changing result dramatically.
Why is this happening? Am I forgetting any setting?
I must use reprot.printtoprinter() method here. Because I am printing the bill receipt. I dont want the user to go to printpreview then click print. AND I must get same result as design on printed page.
Please help me. I am in urgent need.

Hi Don,
Firstly I am very very thankful to you for replying me.
I know I must have irritated you a bit cuz I was expecting everything ready which I should have :P
but I was in urgent need and there was no time for me to read everything. I must say a thing that I did not get good search results on printcontroller when I used search box of this website.
Well Thanks again for helping me in deed.
I am sure this must be the problem for many people across the globe, hence I am posting the exact code that helped me to print the document Accurately:
   rptReceiptAbhishek rptRcAbh = new rptReceiptAbhishek();
        //        rptRcAbh.Load("rptReceiptAbhishek.rpt", OpenReportMethod.OpenReportByTempCopy); i did't need this line
//////// Directly Entering data to the fields of the report.
                CrystalDecisions.CrystalReports.Engine.TextObject txtname;
                CrystalDecisions.CrystalReports.Engine.TextObject txtaddress;
                txtname = (CrystalDecisions.CrystalReports.Engine.TextObject)rptRcAbh.ReportDefinition.ReportObjects["txtRptName"];
                txtname.Text = cboInitials.Text + " " + cboDonarName.Text;
                txtaddress = (CrystalDecisions.CrystalReports.Engine.TextObject)rptRcAbh.ReportDefinition.ReportObjects["txtRptAdd"];
                txtaddress.Text = txtAddess.Text;
                rptRcAbh.PrintOptions.PrinterName = Properties.Settings.Default.PrinterName;
                System.Drawing.Printing.PrintDocument pDoc = new System.Drawing.Printing.PrintDocument();
                CrystalDecisions.ReportAppServer.Controllers.PrintReportOptions rasPROpts = new CrystalDecisions.ReportAppServer.Controllers.PrintReportOptions();
                CrystalDecisions.ReportAppServer.ReportDefModel.PrintOptions newOpts = new CrystalDecisions.ReportAppServer.ReportDefModel.PrintOptions();
                pDoc.PrinterSettings.PrinterName = Properties.Settings.Default.PrinterName;
                pDoc.PrinterSettings.SupportsColor.ToString();
                //if (pDoc.PrinterSettings.SupportsColor)
                //    MessageBox.Show("Printer Supports Color", pDoc.PrinterSettings.SupportsColor.ToString());
                rasPROpts.PrinterName = Properties.Settings.Default.PrinterName;
                //   rasPROpts.PaperSize = (CrPaperSizeEnum)pDoc.PrinterSettings.PaperSizes[cboCurrentPaperSizes.SelectedIndex].Kind;
                //rasPROpts.PaperSource = (CrPaperSourceEnum) pDoc.PrinterSettings.PaperSources[cboDefaultPaperTrays.SelectedIndex].Kind;
      //          rptReceiptAbhishek rpt = new rptReceiptAbhishek();
                var rptClientDoc = rptRcAbh.ReportClientDocument;
                rptClientDoc.PrintOutputController.PrintReport(rasPROpts);
                MessageBox.Show("Printing in progress. Make sure that printer is not turned off.", "RAS", MessageBoxButtons.OK, MessageBoxIcon.Information);
