A portable printer may seem like an anachronism in a world where you can instantly share digital photos and documents around the world in seconds, but there’s still merit in having a physical copy. Sometimes a legal document requires a physical signature, or a less tech savvy family member needs a picture from your wedding. Inevitably these requests come at the most inopportune time, either when you’re traveling, or don’t have a permanent office in which you can stash a full sized printer. The best portable printers will allow you to accommodate these requests, and many are small enough that you can actually take them on vacation with you if necessary.
