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.

Decent printer
The print quality and speed are great. I currently have several different printers for various needs (laser for work, sublimation for crafting, and this one is potentially replacing my ink jet, for stickers) and this one is faster and a nicer quality print than my similarly priced of a different brand. Sometimes (and for literally no reason that I've been able to identify) this printer decides it doesn't want to print. Exactly like every other printer I've ever owned, connectivity can feel chaotic. Overall, all things considered, I think this a decent value for the money. It was easy to set up and get printing. Minimal packaging. Intuitive design. Up and printing within 5 minutes. I love the ability to print is larger formats. I did not sign up for the free 3 months of ink club, so cannot comment on that. So far, the ink consumption feels typical for an inkjet printer. Overall, this is a yes from me.

requirement: scan codes & down load proprietary app to set up & use all the functions of the unit
SPECS The printer weighs 39.19 pounds.  Overall it is 22.625 x 17.5 x 12.03125 inches.  The output tray extender sticks out 5.875 inches from the unit.  The usable power cord length is 59.5 inches. The unit can use legal [B00006GNXZ], letter [B0B57CKBCT], or ledger [B0017LR3M4] size paper. The control panel tilts up and is a color touch screen. The display is 2.125 x 1.625 inches.  The unit has two sided coping, scanning, and printing. There is a document feeder on the top.  The home screen has menu, copy, scan, trays, supplies, jobs, and help as the main functions.  Firmware updates can be set to automatic, notify, or disabled.  The printer does not come with a user manual.  OVERVIEW The unit comes wrapped in a plastic bag that has handles on each side. I was able to easily lift the printer up myself using the handles and took it to the desk.  The printer is missing some key features that do not make the printer cost effective. There is only one print tray. A fold out rear tray vertical tray is not even there.  Having to constantly change paper size is an extreme inconvenience. There is no USB port to be able to print from or scan documents to a USB hard drive or directly from a camera, which is a disadvantage.    In addition, to utilize all the features a code needs to be scanned and or the H P app needs to be used.  I did not like having to scan a code to set up and connect to wireless connection as well as using any of the scan features of email, network folder, computer, and share point, which makes the scan option useless. I had to download the HP app to set up the printer. When I was done I deleted the app. I do not want numerous apps on my devices.  I found not having a manual for the unit to be a disadvantage.  This is not a user friendly printer with all the code and app requirements.  Using the web address on my laptop and phone, just gave me a link to the play store to download the app again, which I did not want.  The size of the display screen is small. At times I had to touch the menu button more than one time to get it to continue to the next screen.   The unit functioned well printing and scanning. I was able to print from the computer via wireless connection without using the app. The copy function does not require the app or show a code to scan to be able to continue. The document feeder allows for quick copying and scanning, which is an advantage. The rollers did grab a one sheet copy job crooked and the copy was askew on the page which is a disadvantage.  On best, the copy did not come out any better than normal.  The copy images were a poor representation of the original. The copy images were more pix elated making them not as complete and crisp. In addition, the single color grey images were very pale and could barely be seen. I did not sign up for HP instant ink, compatibility. I also disabled firmware updates.

This product prints a lot of black & white, as well as color. Our business requires a lot of ink for our Epson.
