The best portable printer is a great thing to have with you at a party, at a wedding, or at any other social event or family gathering. When you've just captured a great photo on your phone, it's even more special to share it with someone in a physical format – especially as not everyone has a smartphone or social media to see your posts.
The beauty of using the best portable printers, much like the best Instant cameras, is that they enable you to give a permanent physical keepsake to a loved one or friend of a moment you both shared together. Mini prints, in contrast, are priceless souvenirs that people will keep and treasure, small enough to keep in a wallet or phone case, too.
The best portable printers, and even the best iPhone printers, do involve some expense – since the printing packs can be pretty expensive – though the printers themselves are usually quite cheap.
Of course, what differentiates these from the best photo printers and all-in-one printers is their tiny size, and they're smaller still than the best compact printers. And some of them also have an integrated digital camera, so you don't just have to print from your phone!
