Neopost IS-420 Printer Review

Expert review of the Neopost IS-420 printer

Our Verdict:

The Neopost IS-420 is a printer which is certainly worth considering, even though many of you will have perhaps overlooked the Neopost name. However, Neopost is at the forefront of franking equipment as demonstrated by the IS-420. Featuring state-of-the-art technology, the Neopost IS-420 franking machine has plenty to offer and is a fairly affordable product to boot.


If the truth be told, on a purely cosmetic level, the Neopost range has struggled to keep up with a few of its competitors, but the Neopost IS-420 is something else entirely. Offering a sleek, ergonomic and brave design., the IS420 has a wonderful user interface. The subtle colour scheme also makes this a very pleasing printer indeed!


As previously stated, the Neopost IS-420 is a tough little number and one which shouldn't cost you much in order to purchase, particularly online. Designed as a mid-volume digital mailing system, the Neopost IS420 is fast and user-friendly. Simplicity is key to the success of the Neopost IS-420 and the machine itself is lacking in unnecessary buttons and dials whilst results were often very pleasing in our tests. Low noise levels also ensure that the Neopost IS 420 is whisper- quiet and fits comfortably into its surroundings.


The IS420 franking machine will not change your life, this much is true, but the Neopost IS-420 does a great deal for a very reasonable price. As a result, you too could certainly benefit from giving the Neopost IS-420 a go as it offers many top flight features at a very pleasing price, something which cannot be guaranteed where other printers which are currently available on the market are concerned, even other Neopost printers in truth.
