How to Export invoices as pdf and print them through API in Zoho books using PHP or Javascript?

The button should print as described 2 invoice and one packing slip from the invoice details page. The option of changing print copy amount would be good but not so important as I can always use the normal print method to do this if need be. I would like the button to do the printing with no more interaction from the user. just push the button and it prints the copies

invoiceID = invoice.get("invoice_id");

invoicedate = invoice.get("date").toDate();

organizationID = organization.get("organization_id");
invoiceIdList = List();

invoiceIdList.add(invoiceID);

json = Map();

response = invokeurl
[
    
url :"https://books.zoho.com/api/v3/invoices/pdf?invoice_ids=" + invoiceIdList + "&organization_id=" + organizationID

    type :GET

    connection:"books"
];

info response;

just pdf file export not print them
