Printer Driver not found in DriverStore even though the file is there

I have a script that installs printer drivers onto a machine. It has worked perfectly for years up until yesterday. This is the script:

# This script works on Windows 8 or newer since the add-printer cmdlets are't available on Windows 7.

# Download the HP Univeral Printing PCL 6 driver.

# To find\extract the .inf file, run 7-zip on the print driver .exe and go to the folder in Powershell and run this command: get-childitem *.inf* |copy-item -destination "C:\examplefolder" Otherwise it's hard to find the .inf files.

$driversrc="\\10.1.1.21\sysprep\Printer Drivers\ApeosC2570\ffac7070pcl6220420w636iml\Software\PCL\amd64\Common\001\FFSOBPCLA.inf"

Write-Host "Reading from here: $driversrc"

$driver = "FF Apeos C2570 PCL 6"

$address = "10.1.1.31"

$portnamesuffix = "_1"

$portname = "$address$portnamesuffix"

$name = "Admin Apeos C2570"

$sleep = "3"

# The invoke command can be added to specify a remote computer by adding -computername. You would need to copy the .inf file to the remote computer first though.

# This script has it configured to run on the local computer that needs the printer.

# The pnputil command imports the .inf file into the Windows driverstore.

# The .inf driver file has to be physically on the local or remote computer that the printer is being installed on.

Invoke-Command {pnputil.exe -a $driversrc }

Add-PrinterDriver -Name $driver

Start-Sleep $sleep

#Get the infos of all printer

$Printers = Get-WmiObject -Class Win32_Printer

$PrinterPorts = Get-PrinterPort

$PrinterName = $name

# This creates the TCP\IP printer port. It also will not use the annoying WSD port type that can cause problems.

# WSD can be used by using a different command syntax though if needed.

Try

{

Write-Verbose "Get the specified printer info."

$Printer = $PrinterPorts | Where{$_.Name -eq "$portname"}

If (! $Printer)

{

Write-Verbose "Adding printer port."

Add-PrinterPort -Name $portname -PrinterHostAddress $address

Write-Host "$portname has been successfully added."

}

Else

{

Write-Warning "Port already exists."

}

}

Catch

{

$ErrorMsg = $_.Exception.Message

Write-Host $ErrorMsg -BackgroundColor Red

}

start-sleep $sleep

Try

{

Write-Verbose "Get the specified printer info."

$Printer = $Printers | Where{$_.Name -eq "$PrinterName"}

If (! $Printer)

{

Write-Verbose "Adding printer."

Add-Printer -DriverName $driver -Name $name -PortName $portname

Write-Host "$PrinterName has been successfully added."

}

Else

{

Write-Warning "$PrinterName is already installed!."

}

}

Catch

{

$ErrorMsg = $_.Exception.Message

Write-Host $ErrorMsg -BackgroundColor Red

}

Start-Sleep $sleep

#Update the infos of all printer

$Printers = Get-WmiObject -Class Win32_Printer

Try

{

Write-Verbose "Get the specified printer info."

$Printer = $Printers | Where{$_.Name -eq "$PrinterName"}

If($Printer)

{

Write-Verbose "Setting the default printer."

$Printer.SetDefaultPrinter() | Out-Null

Write-Host "$PrinterName has been successfully set as the default printer."

}

Else

{

Write-Warning "Cannot find $PrinterName, can't set it as the default printer."

}

}

Catch

{

$ErrorMsg = $_.Exception.Message

Write-Host $ErrorMsg -BackgroundColor Red

}

Try

{

If($Printer)

{

Write-Verbose "Setting printer defaults."

Set-PrintConfiguration -PrinterName $PrinterName -Color $false -DuplexingMode TwoSidedLongEdge | Out-Null

Write-Host "$PrinterName has printing defaults set."

}

Else

{

Write-Warning "Cannot find the specified printer, can't set printer defaults."

}

}

Catch

{

$ErrorMsg = $_.Exception.Message

Write-Host $ErrorMsg -BackgroundColor Red

}

Get-PrintConfiguration -PrinterName $PrinterName

# This prints a list of installed printers on the local computer. This proves the newly added printer works.

Write-Warning "You must manually set the printer Output Color Preference to Black and White. Do it now!"

get-printer |Out-Printer -Name $name

Write-Host "If all went well a page should be printing out on the printer now."

When I run the commands manually, the error persists. This is the error:

Add-PrinterDriver : The specified driver does not exist in the driver store. dd-PrinterDriver -Name "[Name]" -InfPath "[Path]" PS C:\Windows\System32] At line:1 char:1 + Add-PrinterDriver -Name "[Name]" -InfPath "[Path]" + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (MSFT_PrinterDriver:ROOT/StandardCimv2/MSFT_PrinterDriver) [Add-PrinterDri ver], CimException + FullyQualifiedErrorId : HRESULT 0x80070705,Add-PrinterDriver

I want to know if there is a reason that the driver is not getting found in the DriverStore despite my being able to locate it. And whether others have this issue, it appears as if it's a windows issue.
