Output Data to CSV File with headers

Question

So I'm trying to create a powershell script that outputs a list of computers with their default printers. Here's what I have to far:
cls
$obj = New-Object PSObject
$ComputerList = Import-CSV C:\test\PCList.csv
ForEach ($Computer in $ComputerList)
    $DefaultPrinter = Get-WmiObject -Query "select * from Win32_Printer where Default=True"
    $DefaultPrinterName = $DefaultPrinter.ShareName
        $obj | Add-Member WorkstationName $Computer.Name -Force
        $obj | Add-Member DefaultPrinter $DefaultPrinterName -Force
    Write-Output -InputObject $obj | Out-File -FilePath C:\test\PCList_defaultprinter.csv -Append
It's not formatting the CSV in a workable format. What I'd like is to have 2 columns (Workstation Name and Default Printer Name) but it's not exactly doing that.
Any help would be greatly appreciated!!!

Use Export-CSV instead of Out-File, as in:
cls
$obj = New-Object PSObject
$ComputerList = Import-CSV C:\test\PCList.csv
ForEach ($Computer in $ComputerList)
$DefaultPrinter = Get-WmiObject -Query "select * from Win32_Printer where Default=True"
$DefaultPrinterName = $DefaultPrinter.ShareName
$obj | Add-Member WorkstationName $Computer.Name -Force
$obj | Add-Member DefaultPrinter $DefaultPrinterName -Force
$obj | Export-Csv -Path C:\test\PCList_defaultprinter.csv -NoTypeInformation -Append
