When you say it went bang can you elaborate?
Where was the bang/smoke from inside the printer or near the power plug?
Have you ever used the printer before? Was this the first time using it? How old is it?
If the burnt electronic smell came from the inside of the printer there is really nothing that can be done to fix it. You can try moving it to a different power plug in case there is something wrong with the one its plugged in to, but if something "banged", or more or less exploded, it is unlikely to be worth the cost to repair it over replacing it.
If there was a fuse it would have blown somewhere along the wire/transformer (the box on the power cord), but as this is not where the smell is coming from, it seems the damage was already done and even in the unlikely event there was a fuse, something has burnt out.
If you have any other questions please let me know. I am sorry I can not offer better advice but if the printer more or less blew up there is not much I can do to assist, and repairing it will cost more than just replacing the printer. If my advice was helpful, please give me a rating. If you have any other questions, please ask! Thank you!
