Is there any way to write the external CSS for the rendered pdf ?
This code is working fine in local but not working in server,
getting this error - "error":"Failed to launch the browser process

it's what you will use to access the get route created at the server.js, the print.js sends a get request to that route in order to get the html content from it, to create the pdf
