HP Deskjet 3720 All-in-One printer is rated 4.3 out of 5 by 25.
Rated 5 out of 5 by from Fab Printer I was looking for an AirPrint printer so that it was easy for me to print out straight from my mobile. I was fed up of going to the Library or my mums to print out something. I was a bit unsure at first because I wasn’t sure how easy it would be to set up. I didn’t need to worry because once the HP app was downloaded it was so easy, even I could do it!! And although I have yet to experience how the HP instant ink really works, the concept is fab and much cheaper than buying ink cartridges. I haven’t used the scan or photocopy option on it yet but for printing straight from your phone it is great. Never thought I would get so excited about a printer and it is so small and compact. Keep on telling everyone how great it is. If anyone is thinking of buying this printer I would definitely say ‘yes’ go and buy one

Rated 5 out of 5 by from Brilliant This printer is compact, amazingly easy to set up on both iPad and laptop, even I did it by myself. It prints documents clearly, which is what I wanted it for. I haven’t used it for printing photographs so cannot comment about that. It has got a scanner/copy but this is not a flat bed, you feed the document through a slot so wouldn’t be any good if you wanted to copy anything other than a single sheet of paper. Does not print double sided, but is perfect for what I need.

Rated 4 out of 5 by from Good for the price. Was pleased software was included until I found my disc drive has stopped reading discs. I tried the web sites quoted but couldn't find how to download. Thankfully we have an old computer we don't use which disc worked in & I was able to get the http from that. From then on installation was easy. I don't know how people with no disc drive manage. Printing is a bit slow but it is nice & clear. Great for amount of printing I do.

Rated 5 out of 5 by from Small and perfectly formed First things first, this is a small printer! It's footprint is narrower and only slightly longer than a sheet of A4 and fits nicely below by TV with the set top box, out of the way. We are a mobile household, without a laptop, so I was delighted to find that all the printer set up can be done with an app - android or apple - with no need for cables. Thereafter, the printer appears on my network as an Airprint device on iDevices, or as a Direct Print device on android. Scanning too is wireless, working through an easy to use app. I managed to set everything up in 5 minutes, including downloading the app! So far, performance seems good, with clear colours and deep blacks, with no annoying banding in sight. Printing is a perfectly acceptable speed for an inkjet. Scanning too is very quick and good quality. I'm very impressed with this little guy so far.

Rated 5 out of 5 by from Does what it was purchased for I already have an HP 4650 which is a great printer, but because it takes the paper round the platen, it won't print business cards or thick card. this 3720 looks good, is economical and does exactly what I bought it for, and much more besides. It was easy to set up and link wirelessly to my pc and laptop, and the inks are a reasonable price. All in all, it is a perfect little printer and I couldn't be happier with it.

Rated 5 out of 5 by from Superb little printer I am surprised how small and neat this little printer is, it easy to set up and is wireless which is great, you can use all your devices to print from, plus plug it in any room in the house and print away, I've not tried any photo printing yet, but I'm sure they'll be just as good. It prints and scans very well indeed, and the space you can save is also beneficial. I'm impressed.

Rated 4 out of 5 by from Nice little printer Product arrived and was neatly packaged. An real excessive amount of paperwork, several copies of the same marketing material for the HP instant ink service which i found very frustrating given there is a leaflet about how to reduce environmental impact!!! Setting up the printer was very easy, instructions were clear, concise and easy to follow. I struggled with downloading the app so opted for the downloading to laptop version. The only bit that puzzled me was that the printer printed out a welcome sheet listing some information for me.....it was all in German!!! When i set up the account i stated United Kingdom as country but for some reason it printed out in German. The cartridges are small but easy to install, paper easily slotted in the compartment and even with both paper sections out the printer is small and sleek in size. I am not too much a fan of the blue colour used, personal preference i guess but i think it makes the printer look a bit cheap/tacky when i see HP as a quality brand.

Rated 5 out of 5 by from Great This is exactly what I was looking for, good help from lady at Currys. A friend who unlike me, is not technically challenged came and set it up for me, and got my iPad connected. The print quality is really good, and good printing speed.
