Как вы обнаружили, что вам нужно запросить реестр, я использовал [в VBA] , который я получил с Чип Пирсона с отличного сайта Excel :

' Returns an array of printer names, where each printer name
' is the device name followed by the port name. The value can
' be used to assign a printer to the ActivePrinter property of
' the Application object. Note that setting the ActivePrinter
' changes the default printer for Excel but does not change
' the Windows default printer.

Dim Printers() As String ' array of names to be returned
Dim PNdx As Long ' index into Printers()
Dim hKey As Long ' registry key handle
Dim Res As Long ' result of API calls
Dim Ndx As Long ' index for RegEnumValue
Dim ValueName As String ' name of each value in the printer key
Dim ValueNameLen As Long ' length of ValueName
Dim DataType As Long ' registry value data type
Dim ValueValue() As Byte ' byte array of registry value value
Dim ValueValueS As String ' ValueValue converted to String

' registry key in HCKU listing printers
Const PRINTER_KEY = "Software\Microsoft\Windows NT\CurrentVersion\Devices"
PNdx = 0

' assume printer name is less than 256 characters

' assume the port name is less than 1000 characters

ReDim Printers(1 To 1000)
' open the key whose values enumerate installed printers

KEY_QUERY_VALUE, hKey)
' start enumeration loop of printers
Res = RegEnumValue(hKey, Ndx, ValueName, _
ValueNameLen, 0&, DataType, ValueValue(0), 1000)
' loop until all values have been enumerated
Do Until Res = ERROR_NO_MORE_ITEMS
M = InStr(1, ValueName, Chr(0))
If M > 1 Then
' clean up the ValueName
ValueName = Left(ValueName, M - 1)
End If
' find position of a comma and colon in the port name
CommaPos = InStr(1, ValueValue, ",")
ColonPos = InStr(1, ValueValue, ":")
' ValueValue byte array to ValueValueS string
On Error Resume Next
ValueValueS = Mid(ValueValue, CommaPos + 1, ColonPos - CommaPos)
On Error GoTo 0
' next slot in Printers
PNdx = PNdx + 1
Printers(PNdx) = ValueName & " on " & ValueValueS
' reset some variables
ValueName = String(255, Chr(0))
ValueNameLen = 255
ReDim ValueValue(0 To 999)
ValueValueS = vbNullString
' tell RegEnumValue to get the next registry value
Ndx = Ndx + 1
' get the next printer
Res = RegEnumValue(hKey, Ndx, ValueName, ValueNameLen, _
0&, DataType, ValueValue(0), 1000)
' test for error
If (Res <> 0) And (Res <> ERROR_MORE_DATA) Then
Exit Do
End If
Loop
' shrink Printers down to used size
ReDim Preserve Printers(1 To PNdx)
Res = RegCloseKey(hKey)
' Return the result array
GetPrinterFullNames = Printers
End Function
Затем я использую эту функцию, чтобы получить имя принтера PDF:
Public Function FindPDFPrinter() As String
'this function finds the exact printer name for the Adobe PDF printer
Dim Printers() As String
Dim N As Integer
FindPDFPrinter = ""
Printers = GetPrinterFullNames()
For N = LBound(Printers) To UBound(Printers)
If InStr(1, Printers(N), "PDF") Then
FindPDFPrinter = Printers(N)
End If
Next N
End Function
Затем вы устанавливаете Application.ActivePrinter в эту строку.
И если вам действительно нужен порт, вы можете снять его с конца строки.
