While the two-cartridge approach means that replacing empties isn’t as expensive as it might be if the printer used more, it is a little wasteful, in the sense that you’re likely to use up all the yellow ink while there’s a bit of cyan and magenta left in the tank. Two cartridges are required, for black and colour (cyan, magenta, yellow) inks respectively. However, if you want to save some money, an HP Instant Ink subscription can make things a lot cheaper. The average cost per page is around 9-10p. The HP DeskJetPlus 4120 costs about as much to run as a lot of printers in this price range, which is to say it’s quite expensive.
You can manually offset this, but a bit of trial and error is required. The only issue I had with glossy prints was that getting images to align in the centre of 10 x 15 cm paper didn’t always work when ‘fit to page’ was selected on the mobile apps. The mobile apps are a lot of fun, as you can print anything stored on your device – from photos of your pets and holiday panoramas, to selfies and memes – and images can be cropped, tweaked, and enhanced with filters before you press the big ‘Print’ icon. Once HP Smart for iOS and Android is installed, you’ll be set up to print from your phones too, though again AirPrint means the 4120 should show up on an iPhone or iPad without installing anything.

Windows users may need to download and install the relevant drivers in order to send print instructions to the HP DeskJetPlus 4120, whereas macOS users won’t have to, as it’s an Apple AirPrint compatible printer, so can just add the printer to your list of devices as they normally would. Once setup is complete, and you’ve connected the printer to your Wi-Fi network, sending print jobs to the printer via Wi-Fi is a piece of cake.

This can take some time, so allow yourself around 15-20 minutes in total to get everything done. Download the app on your device, connect everything up, turn the printer on, and wait for the software to detect the printer. Setting up the HP DeskJet Plus 4120 is best done on a Windows or Mac desktop or laptop connected to the printer via a USB cable, using the HP Smart app.
