  • Hi. I bought a colour and black set last October (for my HP Deskjet 940c) but I only want to reorder the colour. Can you help?

    Reordering Deskjet 940c cartridges

    Yes, if you log into our "SpeedyReorder" function you should be able to amend your order so that you're purchasing a single colour cartridge rather than a black and colour multipack for your Deskjet 940c printer. Alternatively, you can click on the item you need and select "Add to basket" to start a new order. You can either use a HP 78 colour cartridge or a HP 78XL high capacity colour cartridge in your printer. For the direct link to these items please see:

  • I have an older HP Deskjet 940c printer and my local supplier no longer have the ink cartridges in stock. When trying to source new ones, I'm confused as to the codes e.g. on the ones needing renewal there are codes C6578JE on the 78 tri-colour cartridge and C6615NE on the black 15 cartridge. I've found, for example, C6578** but what and how significant is the "JE". If it says compatible with 940c does this mean it's the same?

    Deskjet 940c ink cartridge codes

    Not necessarily, the suffix of a HP manufacturer code can be important as it can distinguish between a standard or a high capacity cartridge. For example, the HP manufacturer code for the standard capacity HP 78 tri-colour ink cartridge is "C6578DE" whereas the code for the high capacity HP 78XL tri-colour ink cartridge is "C6578AE". We don't currently list a cartridge with the manufacturer code "C6578JE" which suggests that your pirnter might not have been purchased in the UK. We can only supply ink cartridges with UK manufacturer codes and they only work in a HP Deskjet 940c printer that was purchased in the UK. If your Deskjet 940C printer was purchased in the UK then you can use any of the cartridges listed on this page in your printer. The normal configuration of cartridges is to have one black and one tri-colour cartridge installed at any one time. However, you can choose whether you want to use a standard capaciity or high capacity for each coour, each will have their own unque manufacturer code e.g. C6578AE is a HP 78XL high capacity tri-colour cartridge.

  • Where in Johannesburg can I get a new black and white cartridge for my HP Deskjet 940 printer or a refill one? Thank you.

    Deskjet 940c cartridge availability

    Cartridge Save is an online ink retailer based in the UK and we're unable to deliver outside of the United Kingdom. Unfortunately, we can't advise you of where to buy a Deskjet 940c cartridge in Johannesburg so you'll need to contact HP directly for further help with this enquiry. Please be aware that the cartridges we stock will have a different number to those used in a Deskjet 940c printer that was purchased outside of the UK.

HP Deskjet 940c Printer Review

Expert review of the HP Deskjet 940c printer

Our Verdict:

This affordable inkjet printer is a no-frills entry-level device for personal use. The user-friendly HP Deskjet 940c is built for basic printing needs and has been integrated with some new additions to improve its efficiency, but its flimsy design and cheap hardware makes it unsuitable for heavy use.


The HP Deskjet 940c looks like a sleek and compact breadbox with a collapsible 150-sheet capacity paper tray and a control panel with 4 indicator lights and 3 buttons. Installation is quite easy; even beginners can install and run this device. It features a built-in 2MB memory, and the maximum resolution for colour prints is 1200x2400 dpi. The HP Deskjet 940c is rather light at 12.9 pounds and compact at 14.5 inches deep and 17.32 inches wide.


The HP Deskjet 940c can pass as a plug-and-play device with a USB connection, so it is easy to install and use. The comprehensive driver enables booklet printing, banner, and poster media. Optional attachments allow the HP Deskjet 940c to do duplex printing. Colour prints come out at 10 ppm in 'draft' mode. This printer is fairly quiet, too.


The warranty of this device is only good for 90 days. The manual that comes with the HP Deskjet 940c does not say much, so users have to download a comprehensive one online. Cartridge alignment is sometimes a problem. Photo quality is not very good; many users complain of grainy output.
