OK, that's also true, so it made me think, why not check the shopping list before walking out of range of cell or Wi-Fi, and take a screenshot of shopping list showing on Alexa app; too long, just scroll down and take another screenshot. One has essentially "printed" the shopping list and no trees were harmed in the process, either.
I have been in stores like Costco where no radio frequency can penetrate those massive walls of that enclosure.
