The best way to print your promo would be to send the print-ready files to a local print shop nearby (especially for banners). Our files are set up for professional printing with bleeds and crop marks.
There are some print assets that you can print on a home or church printer (e.g. postcards, posters). You can print and cut them out based on the crop marks that are already included.
If you are trying to print more than one image on a page, but only one image is showing, check your "Printer Settings" and choose one of the options (eg. 4 per page).
