Design & Construct

The HP DeskJet Plus 4120 measures more or less 200 x 428 x 332 mm. It’s no longer a standard cuboid, because the entrance aspect is angled forwards, making the DeskJet Plus 4120 appear to be a Sandcrawler, which might be a plus for Big name Wars lovers. 

An automated report feeder (ADF) sits up at the most sensible, above the scanner mattress. Not like numerous all-in-one printers, the place the cartridge cradle (proven under) is accessed via popping the hood, the whole thing is hidden in the back of a panel which sits in the back of the principle paper out-tray. Each time it’s time to interchange 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 – it will dangle as much as 60 sheets of A4, whilst the ADF can dangle as much as 35 sheets of A4. The out-tray folds down with a bit of further arm which swings out to the precise. There are tips and marks all over the place and in the principle hopper a blue plastic slide is helping you line the whole thing up correctly. 

A small LCD show at the right-hand aspect permits you to test ink ranges at a look, however no longer a lot more than that. For daily operations – in addition to in truth surroundings the HP DeskJet Plus 4120 – you’ll be the usage of the HP Sensible desktop and cell apps.

Setup, apps & wi-fi printing

Putting in the HP DeskJet Plus 4120 is best possible achieved on a Home windows or Mac desktop or computer attached to the printer by way of a USB cable, the usage of the HP Sensible app. Obtain the app for your tool, attach the whole thing up, flip the printer on, and look ahead to the instrument to locate the printer. 

This may take a little time, so permit your self round 15-20 mins in overall to get the whole thing achieved. As soon as setup is entire, and also you’ve attached the printer in your Wi-Fi community, sending print jobs to the printer by way of Wi-Fi is a work of cake. 

Home windows customers would possibly wish to obtain and set up the related drivers with a view to ship print directions to the HP DeskJetPlus 4120, while macOS customers gained’t need to, because it’s an Apple AirPrint appropriate printer, so can simply upload the printer in your record of gadgets as they generally 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, regardless that once more AirPrint approach the 4120 will have to display up on an iPhone or iPad with out putting in anything else.

The cell apps are numerous a laugh, as you’ll be able to print anything else saved for your tool – from footage of your pets and vacation panoramas, to selfies and memes – and photographs can also be cropped, tweaked, and enhanced with filters prior to you press the large ‘Print’ icon. 

Sending print jobs over Wi-Fi is in large part hassle-free, and if you wish to position the DeskJetPlus 4120 in a nook the place Wi-Fi sign is not the most efficient, in all probability it’s time to spend money on a brand new Wi-Fi router, or a mesh Wi-Fi device. 

Each cell apps allow you to print recordsdata saved in cloud products and services too, even if the iOS app these days helps a much wider vary of names – Google Force, Google Pictures, Evernote, Dropbox, Fb, Field, plus iCloud vs. Google Force, Google Pictures, Dropbox and Fb make stronger at the Android app. 

Whilst those apps will allow you to check out how a lot ink is left within the tank, they’re restricted when it comes to printer diagnostics – you’ll be able to’t blank the printer nozzle or realign the printhead if it begins generating misaligned photographs. For all of that form of factor, you’ll wish to use the desktop apps. 

In spite of everything, it’s price bringing up that the HP DeskJet Plus 4120 helps Mopria, a cross-platform typical this means that that Android customers can temporarily and simply ship paperwork and photographs to the printer (with out putting in HP’s app) with a easy faucet of the ‘Percentage’ icon in maximum apps, like your telephone’s local gallery, Adobe Acrobat Reader, Google Doctors, and others. 


The DeskJet Plus 4120 is lovely nippy. The reliable spec sheet guarantees to print 8.5 pages in line with minute when printing undeniable textual content, and in my assessments, it in truth did a bit of higher. 

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

It’s a bit of slower at printing anything else in color, regardless that. A 20-page report with textual content and color graphics took 3 mins and 58 seconds, which is more or less 5 pages in line with minute. 

Pictures published on undeniable A4 tackle moderate 53 seconds, whilst printing on 10 x 15 cm shiny picture paper took longer, round 1 minute 10 seconds. 

High quality of textual content used to be satisfactory, however no longer precisely unbelievable on Commonplace high quality. Serifs every now and then appeared vague, and there used to be occasional bleed on letters like ‘okay’, ‘x’, and ‘w’. High quality is most effective actually appropriate on Very best, which after all, makes use of extra ink and approach you will have to wait slightly longer for pages to emerge.

Fortunately, graphics and footage are each superb, with giant blocks of color on bar graphs, trademarks, and diagrams taking a look sharp and ambitious. Pores and skin tones on footage glance life-like, even on undeniable paper, and footage published on glossies glance lovely unbelievable.

The one factor I had with shiny prints used to be that obtaining photographs to align within the centre of 10 x 15 cm paper didn’t at all times paintings when ‘are compatible to web page’ used to be decided on at the cell apps. You’ll be able to manually offset this, however slightly of trial and blunder is needed. 

Operating prices

The HP DeskJetPlus 4120 prices about as a lot to run as numerous printers on this value vary, which is to mention it’s fairly pricey. The common price in line with web page is round 9-10p. Then again, if you wish to avoid wasting cash, an HP Speedy Ink subscription could make issues so much inexpensive. 

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

Whilst the two-cartridge method implies that changing empties isn’t as pricey because it may well be if the printer used extra, this can be a little wasteful, within the sense that you are most probably to make use of up the entire yellow ink whilst there’s slightly of cyan and magenta left within the tank. Until you might be satisfied to proceed printing with the lacking yellow, then you’ll be able to 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 price £10.99 a work and can, on moderate, provide you with sufficient ink for 120 (black) and 100 (color) sheets, which is more or less an identical to a price in line with web page of 9p and 10p, every.

You’re additionally nudged within the route of signing up all over the setup procedure, and each time you test the ink ranges by way of the HP Sensible app, too, so it’s no longer as though discovering a hyperlink to the HP Speedy Ink pages is strictly onerous.
