Incredible image quality even when enlarged to full capacity
The quality and reliability of HP OfficeJet printers is unmatched, from my experience. I use this printer for regular everyday things like return labels and printing out documents but my favorite thing to use it for are art and design projects. I am able to copy an image and enlarge it up to 400%, or minimize its size to 25% which is an incredible range and perfect for design and art projects. As long as the ink cartridges are all at full capacity my images always come out flawless, even when I enlarge them huge. As long as I send an image in the right format or copy from a hard copy image it is always clear and crisp, not pixalized. Our craft room/office is in the basement and I am easily able to print from my kitchen or bedroom from my phone or laptop which is very convenient. The array of functions, the quality of the image, and the bright beautiful rich colors this printer is able to produce is really great if you plan to use it for design or art. I have never had a paper jam, which is very impressive considering I am always changing to photo paper as well as multiple different sized paper. I just received this printer but the HP printer I was using before still works like a charm and is close to 20 years old, if you are using this for your home I can't imagine having to replace it. My absolute favorite part is a 4 pack of extra large ink is $47.99 which is almost half of what my other printers ink cost. The wide format and large paper size I am able to print on has made our art projects really beautiful and uniform, rather than having to try to hide the seams of multiple pages taped together. Incredible product.

Pray you don't need HP Support to set up printer
HP Support is the absolute worst. If you have any setup issues with your HP printer, you're on your own. Their support is practically useless. I’ve been on a two-hour call trying to get wireless printing working. I’ve been transferred to three different people, and none of them knew how to help. Now I’m stuck on indefinite hold (over 30 minutes and counting) with no resolution in sight. I can print fine with a USB cable, but it simply will not print wirelessly no matter what we try. Extremely disappointed and frustrated with HP right now.

Very capable large format color inkjet printer
This thing is big. It’s replacing our Brother color laser, which didn’t get a lot of use (but is great for quick and cheap prints). The HP is longer in one dimension but less tall, so is roughly occupying the same space but with more wall visible (so looks less intrusive). Heavy. I could (and did) lift it on my own but all the packing and instructions say for 2 people to lift it. It’s manageable but I see why there’s that warning. Build quality is mostly plastic but sturdy enough for a static object. Scan lid opens easily, trays extend smoothly etc. Feels well build overall, no concerns. You can download installation instructions using a QR code and it’ll guide you to also install the HP app. The app ideally requires an account, mandatory if you plan to free trial the Instant Ink I think. I had an existing old HP account and used that. The setup was way enough but there’s a weird UI step in the app during pairing where the setup modal is blank grey with a greyed out “Next” button. Looks like it can’t find the printer. Wrong! Just hit Next to proceed. Weird and stupid and I wasted time figuring it out. Loses a star for that. Other than that, setup went fine and test print came out decent. WiFi connected ok and it also has Ethernet. The Brother only has WiFi but is flaky / goes to deep sleep too often. Testing with WiFi has been fine but I feel better knowing I can hardwire into my switch if there are issues! The HP shows on the network as an AirPrint target, and my Mac found it without issue / set up its own drivers. The fold out touch screen is nice, I wish it could be angled horizontally and not just vertically but it’s fine and responds predictably to touch. Colors and text are bright and crisp. Not quite laser crisp but pretty darn close to these old eyes. The colors are also better / truer in my opinion. Had issues with feeding vinyl sticker paper sheets, which repeatedly generated paper jam messages (at no point was the paper jammed) and wasted a lot of time. Willing to blame the paper / media (it’s slightly tacky) but our laser handled it ok. When it finally did print, I noticed some print quality issues / flaws repeatedly in the same places. Unsure of the cause and doesn’t impact subsequent printouts on other paper. Really like the ability to print larger (A3!) size. Note that scanning does not accommodate larger papers (up to Legal / same as the Brother). The supplied ink installed easily but they shipped me more as part of the Instant Ink trial. Subscribed to the lowest tier, which is affordable-ish (they just raised the lowest tier to $1.99 for 10 prints per month) but still costlier than laser. Not a huge fan of vendor lock-in / subs but did see in the fine print that HP allows third party inks to be used, which is reassuring if the subscription doesn’t make sense long term. While printing, the motion of the printer head caused my desk to shake. Worth bearing in mind if you plan on printing heavily while sharing a desk with it. Noise isn’t too bad, better than the laser printing noise we’re used to (lower frequency noise on the HP). I would not print during a zoom call though (noise + shaking). At time of review, $350 for a large format printer with built in scanning (and Ethernet) seems pretty decent. It’s not a bargain but it’s fair. Need to spend more time with other media and have ordered more paper types to test with. Will update if anything changes my rating but so far I feel like it’s a capable replacement for the color laser given our relatively modest print volume and need for higher quality color prints.

Reliable Wide-Format Office Printer – Versatile, Fast, and Feature-Rich
Reliable Wide-Format Office Printer – Versatile, Fast, and Feature-Rich ★★★★★ The HP OfficeJet Pro 9720 is a strong all-in-one wide-format printer designed for small offices or home office environments that need 11x17 printing capability. It handles printing, scanning, copying, and faxing in one unit, making it a very versatile productivity tool. Print quality is sharp and consistent, especially for documents, presentations, and color graphics. The wide-format support is a major advantage for users who need larger prints like spreadsheets, posters, or marketing materials. The automatic document feeder (ADF) and duplex printing features significantly improve efficiency, allowing for hands-free scanning and double-sided printing without constant manual input. Wireless connectivity is stable and easy to set up, with good support for mobile printing from phones and laptops. It integrates smoothly into typical office networks. Print speed is solid for an inkjet in this category, making it suitable for moderate to heavy office workloads. The included Instant Ink trial is a helpful bonus for managing ongoing supply costs. Overall, this is a dependable and well-rounded wide-format all-in-one printer that delivers strong performance, convenience features, and good print quality for office environments that require flexibility and larger document output.

Definitely Not Your Average Home Printer
What a beast of a printer. First thing to know is this is definitely not your standard little home office printer size. This thing is more small business office sized, so make sure you actually have room for it before it arrives. That said, the quality is exactly what I expect from HP. Setup was super easy and pretty painless overall. One quick tip though: remember to remove the cardboard insert from the paper tray before testing it because apparently I needed that reminder myself. Print quality is excellent, especially for color documents and larger format stuff. Everything comes out sharp, vibrant, and professional looking. The phone app is honestly one of my favorite parts. It makes it really easy to monitor ink levels, print from your phone, and troubleshoot without having to stand in front of the printer pushing buttons and getting annoyed. The touchscreen is responsive, wireless setup was smooth, and overall it just feels like a solid well thought out machine. Definitely overkill for someone who only prints a return label twice a year, but if you print a lot or need larger format printing, this thing is fantastic.
