HP Deskjet 3420 Printer Review

Expert review of the HP Deskjet 3420 printer

Our Verdict:

Designed for home and student use, the HP Deskjet 3420 is a reliable inkjet printer that can deliver crisp text documents and even photos and images. This unit has a maximum resolution of 600 x 600 dpi and it can deliver 10,000 pages per month. The HP Deskjet 3420 inkjet colour printer is small and lightweight. The Hewlett Packard 3420 printer is also user-friendly, but its print speed is very slow.


The compact HP Deskjet 3420 measures 422 x 142 x 182 mm and weighs 2.04 kg. This unit comes in white and black and has extendable paper trays. The HP 3420 colour inkjet printer can handle up to 100 plain sheets and 30 sheets of photo paper. Other types of media it can print on include envelopes, greeting cards, transparencies, and labels. For connectivity, a USB port is offered. Print speed can go as fast as 10 ppm for black and 3 ppm for full colour both on draft mode. Photographs as large as 4 x 6 inches can take about a minute to print.


Users can expect decent-quality and consistent output from the HP Deskjet 3420. This sturdy unit is quite cheap making it an ideal choice for users on a tight budget. The HP Deskjet 3420 colour inkjet printer has affordable running costs, too and requires little maintenance. Users can turn to compatible HP Deskjet 3420 ink cartridges if they find the genuine HP inks too costly, saving money by using non-HP printer ink.


Since the Deskjet 3420 is a basic printer, it does not offer networking connectivity. This printer uses tri-colour ink cartridges and it only works on older operating systems. The HP 3420 Deskjet printer has already been surpassed by other inkjet printers in terms of resolution and speed.
