Overview

The HP Deskjet 3420 is an all-in-one inkjet printer introduced by HP targeting home and small office users. It supports printing, scanning, and copying functions, providing multifunction capabilities within a compact design.

It supports print resolutions up to 1200 x 600 optimized dpi in color and up to 1200 x 1200 dpi in grayscale. The printer connects via a parallel port interface, as USB was not standard at the time.

Limitations

The device lacks modern connectivity options such as USB or wireless interfaces, relying on the older parallel port standard.

Print speed is relatively slow compared to contemporary models, taking over a minute for color pages.

It does not support automatic duplex printing which limits efficiency for double-sided documents.

The ink cartridges have limited page yields leading to frequent replacements.
