Golf League Tracker can print scorecards for your league and you can customize them with a number of options. You must have a round scheduled with players/teams set up in order to print scorecards.
Take a look at this help video on details of tweaking your scorecard printout: https://www.youtube.com/watch?v=_3GxOhjGTns
You can print blank scorecards by generating cards for an already scheduled round, and toggling off a number of the options in the green option bar, such as hiding player names, handicaps, etc.
