Quick Verdict
The Liene Pearl K100 is a pocket-sized instant photo printer built for one purpose: turning phone photos into small, shareable prints on the spot. At around $100, it's the cheapest way to get physical prints without a full photo printer setup. It skips a full-size 4x6 output in favor of compact 2x3-inch prints, a built-in rechargeable battery, and a companion app that lets you print, edit, and add filters or borders straight from your phone. It's a fun, casual gadget rather than a serious photo tool, and it's priced and sized accordingly.

Who This Printer Is For
The Pearl K100 is built for casual, on-the-go printing: sticking a photo in a journal, handing a print to a friend at a get-together, or adding physical photos to a scrapbook without setting up a full printer. It's a popular gift pick and a good fit for anyone who wants something smaller and cheaper than a 4x6 photo printer and doesn't mind a smaller print size in exchange for pocketability.
Who Should Skip It
Skip it if you want standard 4x6 prints, need to print more than the occasional photo, or care about color accuracy and detail. The small print size and simple print engine are built for fun, casual use, not for printing photos you'd want to frame or sell. Anyone who prints regularly will find the per-print cost of the proprietary paper cassette adds up faster than a dedicated 4x6 photo printer.
What People Love
Owners consistently highlight how small and portable it is, easy to toss in a bag and bring to a party or trip. The companion app's filters, borders, and collage options get called out often as making the prints feel more personal than a plain photo. The built-in battery is another common highlight, since it means printing anywhere without hunting for an outlet.
The Legitimate Complaints
The most common complaint is print size, some buyers wish 2x3 inches went further, since it's noticeably smaller than a standard photo. The proprietary paper cassette is also a recurring point of frustration, since the cost per print can't be reduced with compatible cartridges the way an inkjet printer's ink can be. A smaller number of owners mention Bluetooth pairing can be inconsistent between the app and printer.
How It Compares
- Liene Pearl K100 (This Model, ~$100): Pocket-sized 2x3-inch instant prints, the smallest and cheapest option in this comparison, best for casual, on-the-go printing.
- Canon SELPHY CP1500 (Step Up, ~$150-180): True 4x6 dye-sub prints with SD card and PictBridge support, best for anyone who wants full-size instant photos rather than pocket-sized ones.
- Epson EcoTank Photo ET-8550 (Upgrade, ~$600): A full wide-format, cartridge-free photo all-in-one for people printing regularly at up to 13x19 inches, a completely different category and price point.
Step Up: Canon SELPHY CP1500
If you want a full 4x6 print instead of a pocket-sized one, our Canon SELPHY CP1500 review covers a dedicated dye-sublimation printer that costs more but delivers a noticeably bigger, more detailed print.
Ink and Supplies
The Pearl K100 uses a proprietary sticky-back photo paper cassette rather than separate ink and paper, so there's no cartridge to refill or replace independently. Because paper and printing material are bundled into one consumable, Castle Ink doesn't stock a compatible alternative for this printer; replacement paper cassettes from Liene are the standard way owners keep it running.
Frequently Asked Questions
Do I need a computer to use it?
No. It connects to your phone over Bluetooth through the companion app, and prints don't require a computer at any point.
How big are the prints?
Each print is 2x3 inches, smaller than a standard 4x6 photo. Some versions of the paper include a sticky back so prints can double as small stickers.
Does it need to be plugged in to print?
No. It has a built-in rechargeable battery, so it can print without being connected to power once it's charged.
Bottom Line
The Liene Pearl K100 is a fun, affordable way to turn phone photos into small physical prints without committing to a full photo printer. It won't replace a 4x6 photo printer for anyone printing regularly, but for casual, on-the-go use, gifting, and quick prints at gatherings, it's one of the most accessible pocket photo printers available.
