Do I need to print my DTV Visa for immigration at Bangkok Airport?

I received my DTV Visa today from the Vancouver Thai consulate, very helpful office and friendly staff!!! I immediately applied for my wife under my DTV Visa. I am just wondering if we are supposed to print the Visa out (hard copy), or use a cell phone or email digital copy at the BKK Airport? For those that are wondering, I originally applied as a remote worker (digital nomad), but that was declined, it was most likely my fault, but the consulate was very helpful and changed my category to "Soft Power", since I already had a dentist in Hua Hin, and need a lot of work done, I just got them to send me a letter stating my dental work needed, I already have a relationship with the dentist, so it was very straight forward, then everything was approved easily, now I am waiting for my wife's DTV Visa to be approved, I submitted our marriage certificate, bank account information in my wife's name, wife's passport bio data page, recent photo, and proof of Canadian address. This group has been very helpful, I hope I can help some of you here by sharing , any questions, just ask
