no print fields value

Hello and excuse for my bad enghlish...

I have try QUICKpdf and i think that is a wonderful program, but there is a problem that i has not solved.

I have created with acrobat a file with 5 fields.
With VB6 and QUICKpdf i can read the file, and insert or modify the content of my fields.
I can also save te new files, and if i open it with acrobat I can read the content of the fields that i've changed with my program...

the problem is :
when I print the file from my program, the fields are all BLANK !!!!

I've try many solutions, also saved the files, re open and print, but the result is the some. The fields are BLANK !!! 

can you help me ?

this is the code :

Dim ClassName
Dim LicenseKey
Dim FileName, FileNameNew, Instance(5) As Long

ClassName = "QuickPDFAX0712.PDFLibrary"
LicenseKey = "j74gf38u9i88w97zu88w7gb7y"
FileName = "scheda.pdf"
FileNameNew = "scheda_new.pdf"

Dim QP As QuickPDFAX0712.PDFLibrary
Dim Result

Set QP = New QuickPDFAX0712.PDFLibrary  '     CreateObject(ClassName)
Print ("Library version: " + QP.LibraryVersion)
Result = QP.UnlockKey(LicenseKey)

If Result = 1 Then
  Print ("Valid license key: " + QP.LicenseInfo)
  Print
 
  Instance(0) = QP.LoadFromFile(FileName)
  Print "Instance(0) ; "; Instance(0)
 
  Instance(1) = QP.FindFormFieldByTitle("Nome")
  Print "Instance(1) ; "; Instance(1)
  Print "GetFormFieldPrintable : "; QP.GetFormFieldPrintable(Instance(1))
 
  Instance(2) = QP.SetFormFieldValue(Instance(1), "Fabio")
  Print "Instance(2) ; "; Instance(2)
 
  QP.SetFormFieldValueByTitle "Cognome", "Calzeroni"
  QP.SetFormFieldValueByTitle "Indirizzo", "Via Borgomanero, 26"
  QP.SetFormFieldValueByTitle "CAP", "28040 PARUZZARO (NO)"
 
  If QP.SaveToFile(FileNameNew) = 1 Then
    Print ("File " + FileNameNew + " written successfully")
  Else
    Print ("Error, file could not be written")
  End If
 
  QP.PrintDocument "hp LaserJet 1320 PCL 5e", 1, 1, 0
 
Else
  Print ("- Invalid license key -")
  Print ("Please set your license key by editing this file")
End If

Set QP = Nothing
