express - Opening the print dialog from Typescript/ExpressJS -


i have requirement, have received pdf server (typescript + expressjs) , able display user on browser.

i need launch window.print() after pdf displayed.

my current code looks like

res.end(buffer.from(body.tostring('utf-8'), 'base64'));

i tried various options, no use, problem response directly server pdf , no control on response.

i tried alter above code to

res.end(buffer.from(body.tostring('utf-8'), 'base64'), function(cb: any){   window.print(); });

but error

referenceerror: window not defined
