Printing a Web Report Using Firefox Results in Lost Session Variables

Question

I'm  having a problem with Firefox users printing a Crystal Report from a web site. 
The first page of the web site collects information to be used in the report generation, for example, start date, end date, type of report etc.  These are all various text boxes, drop down lists, radio buttons and check boxes.  When the user clicks to show the report, everything works fine and the first page of the report will display. The code behind this page takes care of saving al the session variables into hidden fields on the page so the settings will be accessible when the user clicks to view the next page of the report.
On clicking to view the next page of the report, everything is still fine and the process works beautifully and I've had no problems. 
A new problem has surfaced during the printing of these reports.  Users who use IE6.0 or IE 7.0 do not have a problem, however, users who use Firefox do have a problem.
It seems that the print dialog which appears as part of the the Crystal web control manages to 'lose" the variables which were present on the calling page.  It only does this with the Firefox browser.  Calls on postback to retrieve the variables from the hidden fields result in 0's or empty strings ("").
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init .... ....  If Me.IsPostBack = False Then ... ...        strDiscontinuedOnly = Request.Form.Item("ddlInvStatus")             If strDiscontinuedOnly = Nothing Then                 isDiscontinuedOnly = False             Else                 Select Case strDiscontinuedOnly                     Case 0 'All Inventory                         isDiscontinuedOnly = False                     Case 1 'Discontinued Inventory                         isDiscontinuedOnly = True                     Case 2 'Active Inventory                         isDiscontinuedOnly = False                 End Select             End If Else 'Postback is true             intRequestedReport = Request.Form.Item("fldReportID")             strDiscontinuedOnly = Request.Form.Item("fldInvDiscItemsOnly")             isDiscontinuedOnly = Request.Form.Item("fldInvDiscItemsOnly") ... ... end if

Answer 1

Can't explain it, but here are a few tests;
1) Try to print a saved data report
2) Try to print a report that is not using parameters
3) Try a different printer driver as "default"
4) Enable the option "Dissociate Formatting Page Size and Printer Paper Size" on the report
5) What format do you export to?
