How do I find a channel list, preferably printable, just for MY channels?

I'm managing the account of an elderly relative.  When we signed up for TV service, we were given a list of channels that is printed in a tiny, tiny font that she can't even begin to read.  I wanted to find her one that is accessible to an 80-year-old woman. I went to find her channels online and print it.  I've had zero luck

I know how to find a list of channels at her address.  The problem is that it shows every single channel that she could possibly subscribe to rather than the ones she's actually subscribed to.  That is hundreds of channels with hers mixed in randomly throughout.  That is not at all helpful - she'll spend hours switching to blank channels, and end up frustrated and giving up.  The guide, likewise, shows every channel, and it would take her an hour just to flip through the sheer number they show.

How do I find a printable list that only shows *her* channels?
