Rated 2 out of 5 by Bloober from Nice ink tanks, hp app is horrible I like the print functions of this printer. For everything else, it is a joke that requires you to log into your hp account. I just want to use the multifunction device I purchased without big brother hp trying to help. NO REASON for this except hp trying to make more money. I gues that I no longer have to pay crazy amounts for ink, hp tries to make it up somewhere…

Rated 5 out of 5 by New Teacher 2021 from In Love!!! I received the HP Smart Tank Plus 551 as a present for my 1st year teaching classroom. I love how easy it was to set up. When I don't have my computer in hand, I can easily print straight from my phone with no problem. The color the printer produces is amazing. I will be buying another one next year as a 1st year teacher classroom gift.

Rated 5 out of 5 by Phughes from So easy to set up and use all the features! This is an extremely good printer, copier and scanner all in one. It was so easy to set up and using all the features is very easy as well. I bought this for home use and find more reasons every day to use one of the three options. The paper feed and the document tray are just the right size. Also - and this is a big plus - no more cartridges. No more cartridges ever again. I truly love that part. It works with your home WiFi system so you can print from anywhere without having to go to the printer. I really love this product.

Rated 5 out of 5 by Gertrude 43 from Luke was best installer ever. I tried and tried to install my printer and found it impossible so contacted HP. After 7 calls and being cut off I got to talk to Luke who solved all my problems. Why is it so much harder to install a printer than it used to be????

Rated 5 out of 5 by Megamessage from Ink in a Bottle- What a concept!! I was wary about the ink in the bottles but I think I’m a new fan! I’ve got it set up so I can wirelessly send things to be printed and it works every time. The ink does not appear to dry out in the nozzle so it works every time and I don’t have to clean the nozzles, which we all know uses a LOT of ink! I’ll be interested to see how long the ink lasts, especially the two toner cartridges. I would definitely purchase this item again.

Rated 4 out of 5 by dakotadi from good features, great product, but time will tell for me HP represents longevity, my previous printer has only stopped because my computer no longer recognizes the drivers, which I don't understand as the printer worked until noon then wouldn't print because it stated it was missing a driver. I compared Cannon with the supply of ink, price was comparable, but HP won out because my other HP printer is over 10 years old, remarkable! The sales staff I chatted with told me the photos print well, and I agree I am happy with the quality. I hope it lasts as long as my HP2175 all in one did. The only thing I don't understand is it has to be plugged into my computer in order to print and I am still trying to figure out if it will print from the app on my phone because so far it won't.

Rated 4 out of 5 by Jos G from Good, but slooooow The HP smart tank plus 551 is really smooth and fairly quiet. The print jobs look great and shipping was quick! Only down side is it takes forever for anything to print. 5 pages can take almost 5 minutes. Kind of ridiculous especially for the cost of the unit.

Rated 4 out of 5 by CorvetteDon from Like the tanks rather than cartridges for ink. Although not advertised, this printer and scanner automatically sets up in Ubuntu Linux 20.04. Actually easier than Windows or IOS. Prints from all my LInux, Windows and IOS products, as well, as Samsung Galaxy phones. Has better quality scans and prints than the Epson NX430 that it replaced. Nice looking. Installation of print heads was a little puzzling at first. YouTube video of unboxing and setup is much better than included instructions. All-in-all, fine.

Rated 4 out of 5 by Bill in Chicago from Easy to use, perfect for home use I have been most familiar with laser printers in an office setting, so I was uncertain about the applicability of an ink-jet printer to my business needs. I am pleased that the printer operates flawlessly and is quite intuitive. I am still getting used to the "liquidy" output that is a natural feature of an ink-jet device, but by acquiring actual printing paper (versus the cheaper alternative I first acquired) that concern has disappeared. For home use, this is a very reliable, quality product.

Rated 1 out of 5 by pjmateer from Confusing set up this was not only hard to get set up, but has to be the slowest printer ever. Also can only send one thing to the printer at a time. So if my wife sends something to print mine will not work. I have to wait until hers is completed before i can even send mine to the printer.

Rated 3 out of 5 by Newuser780 from Setup issues, but nice product I just bought product and think I will like it, but I had some problems with the setup/installation. Instructions were all pictures and were not very detailed or easy to understand; and I had to remove and reinstall the black printhead 3 times before getting it aligned properly. Ink tanks were easy to fill and the print quality is very nice.

Rated 5 out of 5 by Horse loving girl from Great features I bought this product last week for my sons homeschooling. I really like the quality of the documents printed and the amount of papers printed for one bottle of ink is very inexpensive. True the printer maybe costly but it is very inexpensive to use compared to ink cartridge . 100% satisfied so far

Rated 3 out of 5 by Tom_123 from So far so good, set up instructions incomplete Finally gave up on the cartridge mess and switched to a tank printer. So far so good but time will tell. The shipping piece holding connected to the ink supply lines had ink in it when I removed it, I narrowly avoided ruining the carpeting. The instructions need to warn for this or changed the order.

Rated 4 out of 5 by Dollie J from Opportunity to streamline set up process I've been buying HP and installing for my employers and also for my home use for decades. I had certain expectations that given the low profile of this equipment would provide a straight implementation. I was wrong. The quality of documentation is not up to par so the set up was not a smooth sail. Major opportunities for improvement in this area. After I finished with setup, it's working just fine. I like the ink filling portion of it in that it will not require frequent replenishment.

Rated 3 out of 5 by PK Frog from Tricky Set Up Local availability followed by tricky setup. Needed help from Tech Support, being left on hold forever and unco-operative Virtual Assistant was not a good start. Tecnician was very helpful. Got it set up with the iMac. One week later, I tried to set it up with my husbands PC. Having trouble with that now. Back to Tech support.

Rated 4 out of 5 by connielouhoo from Nice printer Great little printer. Hope the expectations of not using so much ink will actually come true. The claim is it will last for quite a long time so will see. I print a lot of things but nothing more than the average printer user so am anxious to see if the claim on how long it will last is true. So far I like the printer.

Rated 1 out of 5 by MSquared16 from I expected better So far, I'm overwhelmingly disappointed with this printer. 30 sheet paper supply means I've got to watch it and refill paper throughout large prints. The black print head fails every 6-8 pages--I have to open the printer and take out/re- insert the print head. It's very noisy and has to stop and pump ink every 30 seconds. Color printing is inconsistent and changes density throughout a print cycle. I'll probably return this and go back to a true ink jet.

Rated 4 out of 5 by Patchesonceuponatime from Too soon to tell The quality on the few pages I have printed in the few days I've had the printer is good. I am excited about having a more convenient and economical source of ink available. The ink wells couldn't have been easier to fill. I have a MAC and the new improved method of installing the printer software by letting an HP app do it did not work well. The Smart app stopped during the set up process to say that the software for the printer was not available and referred me back to HP to download the right software. That would have been fine. We've been going to HP and downloading printer drivers for decades. But instead of an option to download, HP linked this printer driver availability back to the Smart app which sent me there in the first place. It took a fair number of attempts, and subsequently time messaging with customer service over a couple of days to get a link that actually worked. That's not a customer service or shipping issue--that's a software issue.

Rated 1 out of 5 by Need to print from Holding off on review I opened my product today and was very excited. I followed page by page instructions and continued to get a paper jam error. I went to virtual agent, reset printer, checked everything for several hours and I am a little frustrated. I called the service center and they will be sending out another printer. Hope it comes fast because I am a teacher and need to start using it. I will wait for my final review once I have received and set up the new printer.

Rated 1 out of 5 by Cee in Sales from Business Owner Bought this a month ago - Very disappointed in how little paper it holds, it scan right from camera's disc, I cannot shrink/expand image with the printer and many other features of my previous HP. And I could NOT find a printer with more extra features. It also took about 2 days using a total of 5 hours to install and 2 computer techs from our remote IT company to get it to work.

Rated 4 out of 5 by Vagabond of Viet Nam from I like the quality of print from the printer, however, I was not happy with the two side print feature. My other printer printed both sides in the print process and I did not have to mess with taking the pages out and turning them over in the tray and restart the print process. I will probably get used to it, just don't like it.

Rated 5 out of 5 by VistaView from Quick and easy install I have had the printer about 3 days. Installing the printer was very easy. Clear easy to follow instructions were so appreciated. Connecting to laptops and other devices presented no problems. The printer is quite and the print quality is amazing. I have already used it for work and to print educational activities for the kids. It is compact so it doesn’t take up much space. It is definitely a smart purchase.

Rated 5 out of 5 by Blissful Bee from Hello Good Buy Nothing but praise so far - easy to set up, prints well without a lot of annoying noises. Really digging the wireless bit; it's so nice to not have it crammed on my desk just to hook up to the computer. Also like the ink fill - the tank system is already way better than cartridge. I am interested to see if the "two years worth of ink" actually holds up, but barring issues with that, def a 10/10 would buy again.
