HP Deskjet 3645 Printer Review

Expert review of the HP Deskjet 3645 printer

Our Verdict:

The Hewlett-Packard name has certainly become synonymous with high quality printing over the years and when the team behind the scenes at this company release a new printer, there is often a level of anticipation that surrounds this release. Thankfully, the HP Deskjet 3645 certainly lives up to the hype and here is the proof.

Design

Firstly, the design of the HP Deskjet 3645 warrants your attention. There is often a fine line between an attractive and interesting printer and one which steals focus in your home or office. Thankfully, the HP Deskjet 3645 treads this line with a degree of sensibility. A simple case and polite colour scheme help to render the HP Deskjet 3645 a unique and subtle number.

Advantages

There have been plenty of positive reviews written about the HP Deskjet 3645 since it first appeared on the market, and they seem to say the same thing; print outs are wonderfully clear and sharp. Whether you are producing text documents or simple colour print outs, the Deskjet 3645 not only produces these items to a high standard, but fairly swiftly too.

Disadvantages

We've struggled a little here because there really aren't any disadvantages to the HP Deskjet 3645. The printer is not only affective, simple to operate and charismatic, it is also very reasonably priced for such a printer. So, all in all, the HP Deskjet 3645 is a fine item and one which is very hard to fault.
