Printing just my channels. Is there a way to view or print out just my channels I subscribe to with my package

They have recently added a printable lineup again, but it is a side by comparison between the packages, not entirely for one package. On the DirecTV box you can set to just "Channels I Get" or even setup a custom favorites list where you hide any of the channels you get but don't watch.

Here is a channel list with the channel numbers:

Info then right arrow to Favorites then select Channels I Get to view only those channels.
