decide if and how you are printing backs - OptrixAU/printathome-python GitHub Wiki

You won't always want to print backs on your cards (many print-at-home games don't need them), but when you do, there are several options for exactly how you can do it.

Use the --nobacks parameter if you want to prevent backs from being printed all-together. Note that while some games (such as Agent Decker) really don't need card backs, other games actually require them.

If you are going to print on both sides of your paper, you can use the --backs parameter. This will generate extra images for the backs of each of your cards.

Note that if your cards don't actually have images for their backs, it will print the card again on the other side.

If you are planning on folding your cards (which makes them twice as thick, which is useful if you are printing on standard paper), you can use the --flipbacksx or --flipbacksy parameters. These print each back next to the front. The 'x' version will place the back of the card each card to the right of each front. The 'y' version will place the back of the card underneath each front.

You can swap the sides using the --flipalt option to switch this around so that it places the back on the left or top, if you would prefer.

You can also use the --flipmirror parameter to turn on mirroring for the back. This makes the back mirrored relative to the front. You can also directly control these with --backhreflect (reflect on the horizontal axis) and --backvreflect (reflect on the vertical axis). Generally, these options aren't frequently used on cards and are more often found on standees.
