Print command not working on specific printer if its not default

Question

Im a little confused by this. If I use the Get-printer command I get the printers list. So I know the printer is there.

Get-Printer

Name                           ComputerName    Type         DriverName                PortName        Shared   Published  DeviceType

But I make the command.

start-process -filepath "$root\UNB\FINAL_TEXTO\$archivo" -verb print | out-printer -Name "UNBILLING"

The print job will not be sent if the printer is not set as DEFAULT. I don't want that, I want to send it to the specific printer not matter if its default or not.

Any help is appreciated.

The cmdlet out-printer is writing raw data to the printer with no formatting. The printer you are using wants to see PDF data and if not PDF will not print.

That's not the case the printer prints fine as long as it is the default printer. If it's not, even if I command to print it in that particular printer it won't do it — Juan Manuel Sanchez, Dec 11 '22 at 03:05

You need to first find the printer currently set as Default in order to change that (temporarily) to the printer you want to be used.

For that you can use CIM:

# get a list of printer objects and select the current Default and the 'UNBILLING' printers
$allPrinters    = Get-CimInstance -ClassName Win32_Printer
$defaultPrinter = $allPrinters | Where-Object { $_.Default -eq $true }
$printerToUse   = $allPrinters | Where-Object { $_.Name -eq 'UNBILLING' }

# temporarily set your printer as Default
$null = Invoke-CimMethod -InputObject $printerToUse -MethodName SetDefaultPrinter

# now start the application for thw $archivo filetype and invoke its 'Print' verb
Start-Process -FilePath "$root\UNB\FINAL_TEXTO\$archivo" -Verb print

# after printing, restore the previous default printer
$null = Invoke-CimMethod -InputObject $defaultPrinter -MethodName SetDefaultPrinter
