Your purchase will include 4 digital papers, sized 5x5 inches (or 12x12 cm)---these are perfect for printing card size without wasting ink and paper.
As a bonus, you will also recieve a PNG (with no background) of the heart bats so that you may layer them on the paper or images---see the first sample.
Many people are worried about printing for themselves, but it doesn't have to be scary. The key is good paper ---which doesn't mean expensive. I do all my printing on an Epson 1400 inkjet using Hammermill Color Copy from the office shop, or online. Watercolor paper also works well if your printer can handle the thickness.
