i have been using the openprinter method to gather printer information just move over to office 64bit now the function fails.
Any solution
Private Type PRINTER_DEFAULTS: pDatatype As String: pDevMode As Long: DesiredAccess As Long: End Type
Private Declare PtrSafe Function OpenPrinter Lib "winspool.drv" Alias "OpenPrinterA" (ByVal pPrinterName As String, phPrinter As Long, pDefault As PRINTER_DEFAULTS) As Long

   Dim pDefault As PRINTER_DEFAULTS: With pDefault: .pDatatype = vbNullString: .pDevMode = 0:  End With

It would be best if you could avoid the 64 bit edition of office.  Microsoft itself is still recommending the 32bit version for most.

 If not, then the call will need to be changed and you'll need to use compiler constants and/or ptrsafe to execute the right code.  That's covered here:

Compatibility Between the 32-bit and 64-bit Versions of Office 2010
http://msdn.microsoft.com/en-us/library/ee691831(office.14).aspx

Read the section "Introducing the VBA 7 Code Base" to see how the compiler constants are used.

There is also a code inspector for 64 bit:

Microsoft Office Code Compatibility Inspector user's guide
http://technet.microsoft.com/en-us/library/ee833946.aspx

 which you can use to run through your code and see what needs to be modified.

also, here are all the new 64 bit calls that were created:

http://www.microsoft.com/download/en/confirmation.aspx?displaylang=en&id=9970

and a list of all the calls that were modified for 64 bit:
http://msdn.microsoft.com/en-us/library/aa383663(VS.85).aspx

Look in this to see if the call was modified.

By the way, I checked and your call is correct....in what way does the call fail?

its return zero and fails to open the printer
 res = OpenPrinter(Printer.DeviceName, mhPrinter, pDefault)

Ah, sorry, didn't catch it first time around, the call is incorrect.   It's:


Declare PtrSafe Function OpenPrinter Lib "winspool.drv" Alias "OpenPrinterA" (ByVal pPrinterName As String, phPrinter As LongPtr, pDefault As PRINTER_DEFAULTS) As Long


  phPrinter is LongPtr, not long

jim this works, I had to replace the pdefault with  ByVal 0&.

i am almost at the end of the routine,copymemory fails

#If VBA7 Then
Public mhPrinter As LongPtr
 Public Declare PtrSafe Function OpenPrinter Lib "winspool.drv" _
       Alias "OpenPrinterA" (ByVal pPrinterName As String, _
                             phPrn As LongPtr, pDefault As Any) As Long
#Else
Public mhPrinter As Long
 Public Declare PtrSafe Function OpenPrinter Lib "winspool.drv" _
       Alias "OpenPrinterA" (ByVal pPrinterName As String, _
                             phPrn As Long, pDefault As Any) As Long
#End If


res = OpenPrinter(Printer.DeviceName, mhPrinter, ByVal 0&)
