Just like the HP Envy Professional 6420, the DeskJet Plus 4120 prints in color at as much as 4800x1200dpi, and as much as 1200×1200 in black ink. Printing at increased resolutions takes longer and makes use of extra ink, however ends in a higher-quality, sharper picture.

The A4 scanner captures paperwork at as much as 1200x1200dpi, and copies of paperwork are scanned at 300x300dpi. This mannequin can print on each side of the paper in order for you it to.

Design & Construct

The HP DeskJet Plus 4120 measures roughly 200 x 428 x 332 mm. It’s not an everyday cuboid, because the entrance aspect is angled forwards, making the DeskJet Plus 4120 seem like a Sandcrawler, which will likely be a plus for Star Wars followers. 

An automated doc feeder (ADF) sits up on the highest, above the scanner mattress. In contrast to loads of all-in-one printers, the place the cartridge cradle (proven beneath) is accessed by popping the hood, every thing is hidden behind a panel which sits behind the principle paper out-tray. Every time it’s time to switch the cartridges, you’ll pull this down, and the cradle will whirr into place. Cartridges clip out and in with little effort. 

Paper is fed in on the hopper which sits on the again – this could maintain as much as 60 sheets of A4, whereas the ADF can maintain as much as 35 sheets of A4. The out-tray folds down with just a little additional arm which swings out to the correct. There are pointers and marks in every single place and in the principle hopper a blue plastic slide helps you line every thing up correctly. 

A small LCD show on the right-hand aspect enables you to verify ink ranges at a look, however not far more than that. For day-to-day operations – in addition to truly setting the HP DeskJet Plus 4120 – you’ll be utilizing the HP Sensible desktop and cellular apps.

Setup, apps & wi-fi printing

Establishing the HP DeskJet Plus 4120 is finest performed on a Home windows or Mac desktop or laptop computer linked to the printer by way of a USB cable, utilizing the HP Sensible app. Obtain the app in your gadget, join every thing up, flip the printer on, and anticipate the software program to detect the printer. 

This may take a while, so permit your self round 15-20 minutes in whole to get every thing performed. As soon as setup is full, and also you’ve linked the printer to your Wi-Fi community, sending print jobs to the printer by way of Wi-Fi is a chunk of cake. 

Home windows customers could must obtain and set up the related drivers so as to ship print directions to the HP DeskJetPlus 4120, whereas macOS customers gained’t should, because it’s an Apple AirPrint appropriate printer, so can simply add the printer to your record of units as they usually would. As soon as HP Sensible for iOS and Android is put in, you’ll be set as much as print out of your telephones too, although once more AirPrint means the 4120 ought to present up on an iPhone or iPad with out putting in something.

The cellular apps are loads of enjoyable, as you’ll be able to print something saved in your gadget – from pictures of your pets and vacation panoramas, to selfies and memes – and pictures might be cropped, tweaked, and enhanced with filters earlier than you press the massive ‘Print’ icon. 

Sending print jobs over Wi-Fi is basically hassle-free, and if you wish to place the DeskJetPlus 4120 in a nook the place Wi-Fi sign is not the very best, maybe it’s time to spend money on a brand new Wi-Fi router, or a mesh Wi-Fi system. 

Each cellular apps allow you to print information saved in cloud companies too, though the iOS app at present helps a wider vary of names – Google Drive, Google Photographs, Evernote, Dropbox, Fb, Field, plus iCloud vs. Google Drive, Google Photographs, Dropbox and Fb assist on the Android app. 

Whereas these apps will allow you to check out how a lot ink is left within the tank, they’re restricted by way of printer diagnostics – you’ll be able to’t clear the printer nozzle or realign the printhead if it begins producing misaligned photographs. For all of that form of factor, you’ll want to make use of the desktop apps. 

Lastly, it’s price mentioning that the HP DeskJet Plus 4120 helps Mopria, a cross-platform commonplace which signifies that Android customers can shortly and simply ship paperwork and pictures to the printer (with out putting in HP’s app) with a easy faucet of the ‘Share’ icon in most apps, like your cellphone’s native gallery, Adobe Acrobat Reader, Google Docs, and others. 


The DeskJet Plus 4120 is fairly nippy. The official spec sheet guarantees to print 8.5 pages per minute when printing plain textual content, and in my assessments, it truly did just a little higher. 

I recorded a page-per-minute fee of 9.3ppm when printing 20 pages of black textual content, which on common took 2 minutes and 9 seconds – sooner than the HP Envy Professional 6420 and Canon Pixma TS7450/1. 

It’s just a little slower at printing something in color, although. A 20-page doc with textual content and color graphics took Three minutes and 58 seconds, which is roughly 5 pages per minute. 

Photographs printed on plain A4 tackle common 53 seconds, whereas printing on 10 x 15 cm shiny photograph paper took longer, round 1 minute 10 seconds. 

High quality of textual content was satisfactory, however not precisely improbable on Regular high quality. Serifs often regarded vague, and there was occasional bleed on letters like ‘okay’, ‘x’, and ‘w’. High quality is simply actually acceptable on Finest, which in fact, makes use of extra ink and means you may have to attend a bit longer for pages to emerge.

Fortunately, graphics and pictures are each superb, with large blocks of color on bar graphs, logos, and diagrams trying sharp and daring. Pores and skin tones on pictures look life-like, even on plain paper, and pictures printed on glossies look fairly improbable.

The one difficulty I had with shiny prints was that getting photographs to align within the centre of 10 x 15 cm paper didn’t all the time work when ‘match to web page’ was chosen on the cellular apps. You may manually offset this, however a little bit of trial and error is required. 

Operating prices

The HP DeskJetPlus 4120 prices about as a lot to run as loads of printers on this worth vary, which is to say it’s fairly costly. The common value per web page is round 9-10p. Nonetheless, if you wish to avoid wasting cash, an HP Prompt Ink subscription could make issues lots cheaper. 

Two cartridges are required, for black and color (cyan, magenta, yellow) inks respectively. 

Whereas the two-cartridge strategy signifies that changing empties isn’t as costly because it could be if the printer used extra, it’s a little wasteful, within the sense that you simply’re doubtless to make use of up all of the yellow ink whereas there’s a little bit of cyan and magenta left within the tank. Until you are joyful to proceed printing with the lacking yellow, you then’ll be throwing away that unused ink.

Regardless, the HP DeskJetPlus 4120 takes each the standard-sized HP 305 black and tri-colour cartridges and the larger HP 305XL cartridges. 

The HP 305 cartridges value £10.99 a chunk and can, on common, offer you sufficient ink for 120 (black) and 100 (color) sheets, which is roughly equal to a price per web page of 9p and 10p, every. 

The bigger HP 305XL cartridges are priced at £19.99 and £17.99. Whereas that’s a bit extra, HP guarantees sufficient ink for about 240 (black) and 200 (color) printouts. All of this provides as much as a decrease value per web page of 8p and 9p. 

Signing up for an HP Prompt Ink subscription is simple sufficient – you simply want your electronic mail handle and financial institution particulars at hand. 

You’re additionally nudged within the path of signing up through the setup course of, and everytime you verify the ink ranges by way of the HP Sensible app, too, so it’s not as if discovering a hyperlink to the HP Prompt Ink pages is strictly arduous. 

The Prompt Ink service is sort of intelligent, as your printer will robotically detect when ink ranges are getting low, and have a contemporary set of cartridges posted out to you (in concept) earlier than you run out utterly. If you wish to avoid wasting cash, these rolling contracts are price exploring. Customary costs are as follows:

15 pages: 99p/month50 pages: £1.99/month100 pages: £3.49/month300 pages: £9.99/month700 pages: £22.49/month
