The HP ENVY 4520 Printer Driver is a multifunction printer that offers a number of functions such as text printing on two sides, scanning and photocopying. The automatic document feeder is a feature that could save users a lot of time and trouble and the machine comes with a smart control panel. Although the HP ENVY 4520 Printer Driver is ideal for people with home offices who primarily want to print photos, the slow print speed and rather low quality of the text printing mean that most offices are likely to find this machine to be somewhat lacking.
