whenever i need to send BTC to binance from paper wallet , How can i do?
That's what your private key is for. You could, for example, just download Electrum[1] (bitcoin wallet), import the private-key[2] and send the coins to whoever you want.
Just make sure no one gets hold of your private key. Don't send them to anyone, be careful with fake popups ana ads, don't download random software, etc...
