HP Sprocket Portable Photo Printer (2nd Edition)

HP Sprocket Photo Printer Review: A Pocket Printer for Phone Photos

Phones have made everyone a prolific photographer and almost nobody a printer of photographs. The HP Sprocket exists to close that gap in the least ceremonious way possible: a device the size of a deck of cards that pairs to your phone over Bluetooth and pushes out a 2×3-inch sticky-backed print in under a minute, without ink, cartridges or a trip to a kiosk. It has been on sale in this second-generation form since 2018, and it has accumulated more than 25,000 ratings at a 4.5-star average in that time, which is an unusually long and unusually steady record for a gadget in this category.

That longevity is the interesting part. Pocket printers are a crowded shelf, and most of the competition is younger and louder about its specifications. The Sprocket wins on a different axis: it is genuinely small, it works the same way every time, and the app has had years of iteration behind it. What it does not win on is image quality, and anyone shopping on resolution numbers alone should read the limitations section before ordering.

Quick verdict: the HP Sprocket photo printer scores 7.8/10 in this SoftPickr review. it is the most pocketable and most consistent option in its class, provided you accept ZINK print quality and the paper cost that comes with it.

Key Specifications

How ZINK Printing Actually Works

There is no ink in this printer, which is the single fact that explains most of its behaviour. ZINK paper contains three layers of heat-sensitive dye crystals sandwiched inside the sheet itself. The Sprocket applies precisely timed heat pulses to activate cyan, magenta and yellow at different depths, and the colour appears from within the paper rather than being sprayed onto it. Nothing can dry out, clog or run out separately from the paper, which is why a Sprocket left in a drawer for six months still prints normally when you charge it.

The practical consequences are good and bad in roughly equal measure. On the good side, prints emerge dry, waterproof enough to survive a spilled drink, smudge-proof, and with a peel-off adhesive backing that turns any photo into a sticker. On the bad side, 313 x 400 dpi across a 2×3-inch sheet is genuinely low, and the dye set cannot reach the deep blacks or the subtle skin tones a dye-sublimation printer manages. Prints look like charming small keepsakes, not like photographic reproductions.

The App, Bluetooth and Multi-Device Printing

Everything routes through the HP Sprocket app, and the app is better than the category average because it has had years to mature. You crop, apply filters, add stickers and text, and send. Pairing is Bluetooth 5.0, and the printer stays connected in a low-power sleep mode rather than dropping off entirely, so the gap between opening the app and the first sheet emerging is short. The listed compatibility floor is iOS 10 and Android 5, which covers essentially every phone still in service.

The feature that justifies the second-generation badge is multi-device printing. Several phones can be paired at once and queue prints to the same Sprocket, with an LED colour indicating whose photo is currently feeding through. At a party or a wedding table this changes the device from a personal gadget into a shared one, and it is the single most-praised behaviour in the long-run review record. An augmented-reality mode in the app can also scan the printer to show the pending queue, which is a novelty rather than a reason to buy.

Size, Battery and Everyday Carry

At 6.1 ounces and just under an inch thick, the Sprocket is genuinely pocketable in a way that most “portable” printers are not. It slips into a jacket pocket, a handbag or the outer sleeve of a backpack without being noticed, and that matters more than any specification on the sheet: a printer you actually carry produces prints, and a printer left at home does not. The 10-sheet paper capacity is the practical limit on a single outing, and spare packs are flat and easy to stash alongside it.

Battery life is quoted loosely by HP and behaves accordingly in practice, but the sleep-mode behaviour introduced in this generation is what makes it usable. Because the printer idles at very low draw rather than staying fully awake, a charge survives being carried around for days between print sessions. Recharging is over USB from any phone charger, so there is no proprietary dock to lose.

Limitations and Compromises

The paper is the real cost of ownership, and the sticker price hides it. ZINK sheets are consumable and they are not cheap per print, so a device bought for under a hundred dollars can quietly cost more than that again over a year of enthusiastic use. Anyone printing at volume should price a few packs before committing, because at high volumes a photo-lab print is both cheaper and better looking.

Print quality is the other honest compromise. At 313 x 400 dpi the output has visible dot structure under close inspection, blacks render closer to charcoal than true black, and pale skin tones can pick up a slight warm cast. On a fridge door or in a scrapbook this reads as character; enlarged, framed, or compared side by side with a dye-sublimation print, it reads as a limitation. The 2×3-inch size is also fixed, with no larger option in the range.

Care, Paper Handling and Longevity

Almost all Sprocket problems trace back to paper handling. Each pack contains a blue calibration card that must be loaded face down beneath the sheets, and the printer reads it to set colour timing; skip it or reuse an old one from a different pack and colours drift. Load a full ten sheets rather than topping up a partial stack, keep the paper flat and dry, and do not fan or crease it before loading.

The printer itself needs little. Wipe the outer shell with a dry cloth, keep the paper slot free of pocket lint, and charge the battery every few months even when the printer is idle so the cell does not sit flat. Prints are dry the instant they emerge and need no drying time, but leave the adhesive backing on until you are ready to stick something, because peeled sheets attract dust immediately.

Who Should Buy It?

• Anyone who wants small physical keepsakes from a phone camera without a trip to a print kiosk.
• Scrapbookers, journal keepers and planner users who need peel-and-stick photos in a standard size.
• Parents and teachers who print for children, where charm matters more than resolution.
• Party and event hosts who want several guests queuing prints to one device.
• Travellers who want a printer that fits in a jacket pocket rather than a suitcase.

Look elsewhere if you want photographic print quality. Buyers who intend to frame, enlarge or archive their prints should be shopping for a dye-sublimation printer that produces 4×6-inch output with continuous tone, and anyone printing in bulk will spend less at a photo lab. This is a device for small, cheerful, disposable prints, and it is honest about being exactly that.

SoftPickr Verdict

The HP Sprocket photo printer earns 7.8/10. It is the most carryable printer in a category that mostly overstates how portable it is, and the second-generation additions – Bluetooth 5.0, sleep mode and multi-device queueing – fixed the two things that made the original frustrating. More than 25,000 ratings held at a 4.5-star average across seven years on sale is a rare kind of evidence, and it points at a product that behaves the same on day 500 as on day one.

It does not earn a badge here, and the reason is the pair of compromises at its centre: ZINK output is visibly low-resolution, and the paper cost accumulates quietly. Buy it for what it is, which is a pocketable sticker factory for phone photos, and it is a pleasure. Buy it expecting photographic prints and it will disappoint on the first sheet.

HP Sprocket photo printer — Frequently Asked Questions

Does the HP Sprocket need ink cartridges?

No. It uses ZINK Zero Ink paper, which carries the dye crystals inside the sheet and activates them with heat. The only consumable is the paper itself, which means there is nothing to dry out or clog between uses, but it also means every print has a fixed paper cost.

What size are the prints and can they be used as stickers?

Every print is 2 x 3 inches with a peel-and-stick adhesive backing, so any photo can be used as a sticker. There is no larger paper option for this model, and the size cannot be changed in the app.

Can more than one person print to it at the same time?

Yes, and this is the main upgrade in the second edition. Multiple phones can pair simultaneously and queue prints, with an LED colour showing whose image is currently being printed. It is the feature that makes the printer useful at parties rather than only as a personal device.

How good is the print quality compared with a photo lab?

Noticeably lower. At 313 x 400 dpi the prints have visible dot structure and blacks that sit closer to dark grey, so they read as keepsakes rather than photographs. For framing or archiving, a lab print or a dye-sublimation printer is the better choice.
