How can we print invoice in odoo 10 without downloading?

While generating invoice in bahmni 0.92, invoice gets downloaded. Instead of downloading, we need to print it from the printer directly without downloading in the first place. It should redirect to the printing page. How can we do that in odoo 10? Previously on 0.91 it used to redirect to printer. If anyone has done this then could u please guide us through?

you will need to install additional module (web pdf preview). Check the configuration doc

It redirects to the preview page but i am trying to get it in the browser download likewise bahmni card print to print from the printer directly. Is there anyway to do that in odoo 10?
