Sharing a fun moment on social media is great, but as we continue to peel off once-sticky platforms, portable photo printers become all the more important for capturing and sharing the memories. This year saw yours truly really valuing the HP Sprocket, which I’ve used to show friends how much I cherish the moments we share on trips and after concerts. I’ll even pack it on a trip, because it doesn’t even need to be plugged in to print; its internal battery charges while plugged in. Oh, and because it uses Zink technology instead of actual ink, you’ll never need to replace cartridges; you’ll just have to buy more packs of printer paper. — Henry T. Casey, electronics writer
