$ACTIVE_PRINTERS = Get-Printer  
try {
    if (Get-Variable -Name LM -ErrorAction SilentlyContinue){
        Write-Host "Lexmark Printers"
        foreach ($PrinterName in $LM.Keys) {
            $ip = $LM[$PrinterName]
            if (!$ACTIVE_PRINTERS.Contains($PrinterName)) {
                Add-PrinterPort "$ip"
                Add-Printer -DriverName "Lexmark Universal v2" -Name $PrinterName -PortName "$ip"
                }
            Write-Host "$PrinterName : $ip Are Mapped"
        }
      
        
    } else {
        Write-Host "No Lexmark Printers Located in $sqdrn"
        }
} catch {
    Write-Error "An error occurred: $($_.Exception.Message)"
}

我正在尝试编写一个脚本，该脚本可以遍历 IP 地址列表并映射打印机和名称，映射和命名方面可以工作，但过滤不起作用，它只是告诉我打印机：ip 对存在并出现错误。即使通过设置和控制面板删除/取消映射打印机。以下是位于 LM 数组中的键值对的示例。

$LM = @{"ROOM#1"="192.168.x.1";"ROOM#2"="192.168.x.2"}

以下是收到的错误。

Add-PrinterPort : The specified port already exists.

我已经尝试了 $ACTIVE_PRINTERS 的 if 语句的许多变体，并且对 powershell 还很陌生。如果有人需要更多信息或者我没有提供足够的信息，请告诉我！
