HP 936 Ink Cartridges Review: Reliable 4-Pack for OfficeJet Printers

Quick Verdict

If you're running an OfficeJet Pro 9130 or one of the other supported models, the HP 936 ink cartridges are exactly what HP designed them to be — consistent, reliable, and straightforward to replace. The four-pack gives you black, cyan, magenta, and yellow in one shot, and the Instant Ink compatibility is a genuine cost-saver for anyone printing more than a few pages a day. I rate this set 4.3 out of 5.

What Is the HP 936 Ink Cartridges?

I grabbed these after my previous third-party cartridges started leaving faint horizontal streaks on longer documents — the kind of thing that looks sloppy on a client proposal. The HP 936 is a four-colour cartridge set (black, cyan, magenta, yellow) built specifically for HP's OfficeJet Pro and OfficeJet lines. It's an original-equipment (OEM) product, not a refill or compatible, which means the firmware handshake with your printer is seamless and the yield figures HP publishes are the ones you can actually expect under normal use.

HP launched the 936 series alongside its newer OfficeJet generation, replacing the older 910-series cartridges with improved formulation for sharper text and better colour saturation. The line is also Instant Ink-registered, meaning HP's subscription service will automatically dispatch replacements before you run dry — provided you've enrolled.

Hands-On Review

Setting up the HP 936 cartridges took about eight minutes. Most of that was peeling tape and cardboard packaging — HP still overboxes these things, which I appreciate from a protection standpoint even if it's not great for the environment. The moment I loaded the black cartridge and ran the alignment page, I noticed the text had regained that crisp, dark quality that third-party options sometimes struggle to replicate. No banding, no light grey ghosts on the letter 'e' at 10pt font.

Over the next three weeks I pushed these cartridges through roughly 400 black pages and maybe 60 colour pages — a mix of school permission forms, a couple of photo prints for a neighbourhood newsletter, and the usual wave of shipping labels. By week three, the colour cartridges sat at about 60% remaining, and the black was still going strong. The per-page cost works out favourably compared to buying individual colours, and the fact that I can buy this exact four-pack without hunting through HP's confusing catalogue is a small but real convenience.

What surprised me was how little I thought about these cartridges once they were in. No warning messages, no mid-print failures, no calibration prompts beyond the initial setup. My previous non-HP set was always triggering some kind of low-ink alert two weeks earlier than expected. That's not an issue here. Will I keep using HP 936? For my use case, yes — though I'd appreciate an XL option for the black cartridge specifically, since that's where most of my consumption lives.

Who Should Buy It?

• Home-office and remote workers who print daily and need reliable, streak-free output without babysitting their supply levels
• Small business owners running an OfficeJet Pro 9130 or 9125e who value consistent colour matching for client-facing documents
• Instant Ink subscribers who want the convenience of automatic replenishment without manually ordering cartridges every few weeks
• Anyone upgrading from an older OfficeJet model who needs the 936 series specifically and doesn't want to gamble on compatible knockoffs

Skip this if you're running a heavily modified or region-locked printer, or if you print less than 50 pages per month and consider even $60 per four-pack a stretch — in that case, a budget printer with cheaper consumables makes more sense. Also skip if you need a high-yield XL variant: HP hasn't released one for the 936 line yet, so heavy-volume black print users may burn through replacements faster than they'd like.

Alternatives Worth Considering

• HP 936XL compatible third-party cartridges: Brands like SmartFill and E-Z Ink sell remanufactured 936-style cartridges at roughly 40% less per cycle. You'll trade some yield and occasional colour accuracy, but the savings add up if you're printing thousands of pages.
• HP Smart Tank system printers: If you're buying a new printer entirely, HP's Smart Tank line uses瓶式墨水 rather than cartridges and delivers dramatically lower per-page costs for high-volume users. Not a cartridge swap, but worth considering for the long haul.
• Epson EcoTank ET-4850: Epson's alternative to HP's OfficeJet line uses micro piezo printhead technology and refillable ink tanks. The upfront cost is higher but running costs are significantly lower if you print hundreds of pages each month.

FAQ

Final Verdict

The HP 936 ink cartridges are a dependable choice for anyone running a compatible OfficeJet model and prioritising print quality over marginal cost savings. The Instant Ink integration alone justifies the OEM premium for moderate to heavy users who don't want to track cartridge levels manually. Page yield is honest, installation is painless, and the ocean-plastic recycling initiative is a small but meaningful nod to sustainability that many buyers appreciate. My recommendation: buy the four-pack when you see it on sale, keep a spare black cartridge on hand, and don't overthink it beyond that.
