Do I need to notorize documents for UK Visitor visa

[traveller32]

Hello All,

I am a Indian citizen living in USA on H1B visa. I will be travelling to India via London and will be staying in london for 3 days during my trip.
I have applied for UK visitor visa and sent following documents:
1. original Passport, I797, employment letter
2. print outs of online bank statements , online pay slips, , online hotel and travel reservation (all not notarized)
3. True copy of Marriage certificate - notarized in india

I want to know if I should have sent notarized copies of printouts that I mentioned in point 2 or is it ok to just send the print outs?
Has anyone done this before and still got the UIK visitor visa?
Please let me know as my travel date is within 6 weeks.

Thanks and appreciate all your responses!!
