Printing generated cards
The generated cards open in a new tab or window. If you don't see any new tab or window, check your popup blocker.
Make sure to use the correct paper size (same as in the editor).
Enable double sided printing (flip on long edge).
Do not scale the document to fit the page.
Some printers are not very precise (pages print slightly shifted or rotated) and the cards will not line up with the card backs.
If this is the case, there's nothing you can do. Try a different printer or print single-sided.
