Probs trying to use snmp to get info from printer

Hi. I am trying to use the get method of the com object "OlePrn.OleSNMP" to
get info from printers. The sequence I've used:
$a=new-object -comobject "OlePrn.OleSNMP"
$a.Open($IPAddressOfPrinter,"public",1,2000)
$v=$a.get(".1.3.6.1.2.1.1.4.0")
This should return the value of the contact. If I watch the net traffic I
see the correct response return from the printer. But in powershell I see
"Exception calling "Get" with "1" argument(s): "WinSNMP API Error: For
internal/undefined errors"
At line:1 char:7
+ $a.get( <<<< ".1.3.6.1.2.1.1.4.0")"
Can anyone suggest how I avoid this error and get the value returned by the
printer?
TIA

Try something like this instead:

$z=$a.open...
$v=$z.get...

Tried that Marco but the $a.open does not return anything so I get "You
cannot call a method on a null-valued expression" from the $z.get.
