The printers I am trying to delete are IPP Printers, so, I could delete them by querying the port instead of the name, so the name becomes irrelevant. I was thinking about doing something on the lines of this, but, it does not work. I might have it all wrong....

SetOption('Explicit','On')
SetOption('NoVarsInStrings','On')
Function ArrayEnumKey($regsubkey)
Dim $retcode, $subkeycounter, $currentsubkey, $subkeyarray
If Not KeyExist($regsubkey)
Exit 87
EndIf
$subkeycounter=0
Do
$currentsubkey=EnumKey($regsubkey,$subkeycounter)
If Not @ERROR
ReDim Preserve $subkeyarray[$subkeycounter]
$subkeyarray[$subkeycounter]=$currentsubkey
$subkeycounter=$subkeycounter+1
EndIf
Until @ERROR
$arrayenumkey=$subkeyarray
Exit 0
EndFunction

Dim $Key,$PrinterKeys,$Value,$Find,$Item,$Data
$PrinterKeys=ArrayEnumKey('HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers')
$Value = "Port"
$Find = "http://IPADDRESS/ipp"
$Data = ReadValue($KEY,$VALUE)
For Each $Key in $PrinterKeys
If $Item = $FIND
deltree($Key+$PrinterKeys)
@error ?
