I'm trying to learn how to use pdfMake. I'm trying to use open and print to generate or print the information respectively. But, when I click on the button which fires the event, a new tab opens for a second and vanishes.
The page which opens is displayed in history as blob:http://localhost:9999/93c1600e-3c64-42fe-8b44-fe6eeb995b5e
I'm not able to figure out the error. I'm following the official documentation of pdfMake.
Please help.
function print(){
window.event.preventDefault()
// this is just a simulation of the open event, replacing it with print produces the same result
var docDefinition = { content: {text:'This is an sample PDF printed with pdfMake',fontSize:15} };
pdfMake.createPdf(docDefinition).open();
