WMI can do it, but I have an issue, PCs are on, but logged off. If I try to run:

```
wmic /node:%strIP% printer where DeviceID="lp1" set DriverName="Lexmark Universal v2"

```

It fails with a message about a "generic failure". I RDP in and then run the same command from my end, and it works. Powershell version I am using is older, so it does not have some of the printer cmdlets, and updating PS is currently out of the question. Is there a way to remotely log someone in, without actually having to RDP in? Via PS, cmd, PSEXEC, etc? 

The other avenue I've taken is using regedit, but I'm hitting some hicups with that, namely that I cannot figure out what to copy. In regedit, I can change the drivername and the setting that enable duplex and tray2 (in printer settings), but I cannot figure how to change the settings in printer preferences for printing double sided and doing so along the long edge. 

What I did to figure out what to change, I did a find on the printer name in regedit as a data value and exported the keys before changing the settings. Then I exported it again AFTER changing the settings. I then used `fc /c /a /u before.reg after.reg` to get the changes. I chopped up the .reg to include only the changed values. Running the .reg seems to change everything, but the print both sides, along the long edge settings. It is a lexmark printer, so I am wondering if maybe preferences for it are stored elsewhere.

This is my most up to date PS1 script. I've commented out some lines as I tried different ways of doing things:

```
$Cred = Get-Credential
$Str = Read-Host "Please select a site ID [###] "
$PC = Read-Host "Please select a PC number [##] "

Clear-Host
$PCNm = "$Str-CCPC-$PC"

function Test-PsRemoting
{
    try
    {
        $errorActionPreference = "Stop"
        $result = Invoke-Command -ComputerName $PCNm { 1 }
    }
    catch
    {
        Write-Verbose $_
        return $false
    }

    if($result -ne 1)
    {
        Write-Verbose "Remoting to $PCNm returned an unexpected result."
        return $false
    }

    $true   
} 

If(!(Test-PsRemoting)){
    PSEXEC \\$PCNm powershell Enable-PSRemoting -force 2>&1 >nul
    Clear-Host
    Write-Host "Enabled PsRemoting"
}else{Write-Host "PsRemoting already enabled"}

Invoke-Command -ComputerName $PCNm -Credential $Cred -ScriptBlock {
    #$lp1 = Get-WMIObject -Query "SELECT * from Win32_Printer Where DeviceID='lp1'"
    $lp1 = Get-WmiObject Win32_Printer | ?{$_.name -eq "lp1"}
    $lp1.Scope.Options.EnablePrivileges = $true
    $lp1.DriverName = "Lexmark Universal v2"
    $lp1R = $lp1.Put()
    #$lp2 = Get-WMIObject -Query "SELECT * from Win32_Printer Where DeviceID='lp2'"
    $lp2 = Get-WmiObject Win32_Printer | ?{$_.name -eq "lp2"}
    $lp2.Scope.Options.EnablePrivileges = $true
    $lp2.DriverName = "Lexmark Universal v2"
    $lp2R = $lp2.Put()
}

#$lp1 = Get-WMIObject -Impersonation Delegate -Authentication Call -Credential $Cred -ComputerName $PCNm -Query "SELECT * from Win32_Printer Where DeviceID='lp1'"
#$lp1.DriverName = "Lexmark Universal v2"
#$lp1.Put()

```

No matter which way I try it, invoke-command, or get-wmiobject, I get:

```
Exception calling "Put" with "0" argument(s): "Generic failure "
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
