Printing problem with Adobe Acrobat 9.3 (SDK) on Windows 7 64 bit

Question

Hi
I have used Adobe Acrobat 7.0.5 SDK (VB.Net with VS 2005) with Windows 2003/XP and printing works fine. I am trying to make printing
work on a laptop with Windows 7/Office 2010/Adobe Acrobat 9.3. I am using SDK , VB.Net (.Net Framework 2.0 with VStudio 2008).
I have added a network printer on the laptop. From the code I set the default printer and then try to print a PDF with the default printer.
The function returns true, doesn;t throw any error but it actually doesn't go to printer. I have tried many ways to print a PDF even from Local Hard disk.
But no luck. Below is the code. Any ideas please.....
Dim PDDocPrint As New Acrobat.AcroAVDoc
            'set default printer name
                     m_sprinterName = p_sPrinterName
                    m_sprintJobnm = Filename
                    If PDDocPrint.PrintPagesSilent(0, -1, 0, 0, 0) = False Then
                        LogError("Unable to print")
                        TerminateAcrobat()
                        Return False
                    End If
                   PDDocPrint.Close(0)
                Else
                   LogError("::Error Desc.: " & "Unable to open PDF file: " _
                                             " for printing.", "")
                    Return False
                End If
The "PDDocPrint.PrintPagesSilent(0, -1, 0, 0, 0)" returns true but printing doesn't happen. I have tried "PrintPageEx" an dother functions.
Is there anything else to do with Adobe 9.0 or Windows 7.0?

Thanks!!! It is version 9.3.1. Should I upgrade for better?
But WHen I tried again changing the parameters as below: trying to print a few pages
l_oCAcroPDDocPrint.PrintPagesSilent(0, 2, 0, 0, 0) - 0 first page and 2 last page. It works fine.
In 7.0 I used -1 in place of last page and it printed all pages of that particular PDF.
I did not find about printing all of these pages from Acrobat 9.0 API. Can you please let me know?
