How do we send a PDF file (which we have path of) to get printed directly without confirmation dialogs?

I am super new to Kotlin app development and I am trying to make an app which generates & sends a PDF to print directly to the once chosen printer... I'm using PdfDocument library to generate a PDF using my printPDF function -

//necessary imports

private fun generatePDF(text: String) {
    val fileName = "badge.pdf"
    val pdfDocument = PdfDocument()
    val pageInfo = PdfDocument.PageInfo.Builder(288, 432, 1).create()

    // .... pdf building code here

    val downloadsDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)
    val badgesDir = File(downloadsDir, "Badges")
    if (!badgesDir.exists()) {
        badgesDir.mkdirs()
    }
    val file = File(badgesDir, fileName)
    pdfDocument.writeTo(file.outputStream())
    pdfDocument.close()

    Toast.makeText(this, "success: ${file.path}", Toast.LENGTH_LONG).show()

    //toast prints like - "success: /storage/emulated/0/Download/Badges/badge.pdf"
}

The above generatePDF function creates & stores the PDF in/as Download > Badges > badge.pdf, which I can access by going into the Download folder in my phone's file manager.

After the toast, I want to send it directly to the printer to get printed, without any page-setup/confirmation/customisation dialogs intervening the process. It would be like I choose the printer once & for all at the very first print, and then it should just directly print the document without asking for choosing printers. So far I've read some stuff about PrintDocumentAdapter, but can't wrap my head around it if it's the one I want and how to implement it....

Is this possible to do in Kotlin, sending a document to be directly printed?
