Script to disable SNMP for all mapped printers

Question

I'm looking for a script to disable SNMP on all printers mapped to a single computer.
I'm fairly new to scripting and I'm having troubles finding if this is even possible. 
We've been going through and disabling SNMP on a few hundred printers, essentially breaking printers already mapped for thousands of users. Re-enabling SNMP is not an option. 
The only scripts I've been able to find require you to specify the printer port and the computer name. 
Basically, I need a script to say "disable SNMP on all printers". 
I also played around with the following registry entry, but it did not disable SNMP: 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print
New DWORD Value.
SNMPLegacy
Set value 1.
I can have the script pushed at login, so as long as it works on a single computer, without needing to specify the port that requires a change, it should work without a hitch. 
I really appreciate any advice you guys may have.

I think this PowerShell code should do the trick.  You can translate it to VBScript if needed (since it's just using WMI, both are fully capable of getting the job done).
Get-WmiObject -Class Win32_TCPIPPrinterPort -Filter 'SNMPEnabled = True' |
ForEach-Object {
$_.SNMPEnabled = $false
$_.Put() | Out-Null
Edit:  Oddly enough, the MSDN documentation on Win32_TCPIPPrinterPort says that the SNMPEnabled property should be read-only, but I just tested this code on my Windows 7 machine and it worked fine.
If, for some reason, you can't modify this through WMI, you can do it directly in the registry:
Get-ChildItem -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Print\Monitors\Standard TCP/IP Port\Ports' |
Set-ItemProperty -Name 'SNMP Enabled' -Value 0
