Hi Kamlesh,
Hope you are doing all good. I believe you meant Printing Engineering when you said Printing. Now, Printing or any engineering branch is got based on the rank in the entrance exam you take for that specific college. It is independent of your 12th marks. However, the college might have some limitations in terms of your 12th marks.
Most colleges limits their criteria to 55% while some allow 50% as well. So you need to be specific in terms of college, where you want admission.
Feel free to add more doubts. All the best.
