No print needed. The details went to immigration authority server and the e-gate will record your biometrics if this is your first time visit to Singapore. All your visa details and the SGAC details you entered got saved in their server against your passport number. Everything is digital and automated. No human immigration officer interaction. That e-gate is the officer, lol.
Take a print out of visa only, not SGAC. This is to show to airline while you take boarding pass, and also to Indian immigration. As these folks don't have your visa details.
There was a news last month that singapore is implementing passport-less immigration. Where your face is your passport. Don't know if it's live already. Once live, you'll need passport for the first time when you enter Singapore and your biometrics will get captured by the e-gate. After that all future visits will not even require your passport. On scanning your face/retina etc the e-gate machine will recognize who you are, whether you have valid visa etc and will give you immigration clearance.
