iGNOU clearly prescibes to go by handwritten assignments, that's what you're required to do, even if you download any assignment question paper for your session, you will find it clearly mentioned that you have to complete your assignments in your own hanwriting.

There isn't any printed form assignments allowed for submission.

Hope, this clears your doubt.

Hello aspirant, 

It would be more helpful to provide you with appropriate details if you have mentioned details as your subject, college you belong to etc...,. 

Hope you understood. 

All the very best for your bright future!!
