Why do the System Requirements for Turbotax Premier 2023 for Windows include a printer?

On Amazon, according to the System Requirements for Turbotax Premier 2023 (disc, for Windows), the software requires an inkjet or laser printer? Why? I want the software to give me a PDF of my tax return to be stored permanently after e-filing. Is the software going to make me hook up a physical printer and print my return in order to file and/or complete the process?
