  • Are your cartridges for the Neopost IS330 compatible or original ink cartridges?

    Compatible or original Neopost IS-330 ink

    We currently only stock a compatible red Neopost IS-330 ink cartridge which acts as a direct replacement for the genuine Neopost cartridge (300620). Our compatible Neopost 300620 ink cartridges for the IS-330 are very reliable and have been approved by Royal Mail.

  • Hi, will the use of your IS-330 cartridge compromise the lease arrangement we have with Neopost? Best wishes, Peter.

    Use of alternative Neopost IS-330 cartridge

    Without knowing the specific terms of condition for the lease of your printer we wouldn't be able to advise whether or not any agreement would be compromised. However, under normal circumstances the use of non-genuine cartridges is fully legitimate and doesn't void the manufacturer's warranty. We guarantee that our compatible Neopost 300620 or 300621 cartridges will work reliably in the printer and in the unlikely event that a compatible Neopost cartridge that we've supplied you with has caused damaged to the machine we would accept liability for any repairs. Our compatible Neopost IS-330 ink cartridges are high quality supplies and have been Royal Mail approved. For more on our 100% satisfaction guarantee, and how we guarantee your printer when using our compatible ink cartridges, please see:

  • After inserting a new IS-330 cartridge, this message came onto the display: "New headset detected . Do you want to do the headset alignment"?

    Message on Neopost IS330 franking machine

    It's likely that your IS-330 printer is asking you to complete a printhead alignment to help install the new cartridge correctly. We would suggest that you should accept this request.

Neopost IS-330 Printer Review

Expert review of the Neopost IS-330 printer 10 May 2012

Our Verdict:

When a printer as odd and as downright random as the Neopost IS-330 hits the market, we get a little excited as we get to try out this odd piece of kit. Yes, the Neopost IS-330 is an item which is set to surprise as well as confuse if we are being fair. However, as strange and as unfamiliar as the Neopost IS-330 is, does this printer offer enough perks to challenge for top spot?


The look of the Neopost IS-330 is certainly worthy of note. In many ways, the Neopost IS330 looks like a shop till! However, as different as the Neopost IS330 is, it's not badly put together. The Neopost IS-330 comes complete with a user interface which warrants your attention, as well as a subtle and understated colour scheme.


The Neopost IS-330 is a professional franking machine so sending high quality mail is what is does best. Forget about spending too much on stamps when you have the Neopost IS300 because franking is estimated to be 38% cheaper. The IS-330 offers plenty of perks, but besides the odd and new nature of this printer, and indeed of the brand in general, the Neopost IS-330 offers some very tidy results. The Neopost IS-330 is a stylish machine, and one which has the goods to match the intriguing look and design of the machine.


In all honesty, the Neopost IS-330 might not appeal to you on a design front, but what this printer does offer is affordability and high quality results. These are two hugely important aspects of any printer of course, so write off the Neopost IS-330 at your peril.
