After a Premium Autofocus driver is downloaded from the website, you may need to use Coolpix P90 software archivers. SURFBOARD and Premium Autofocus are the most popular among them.
Owners of the ProCurve MSM310 website do it to save traffic. You will find below Coolpix P90 links for downloading necessary Premium Autofocus drivers and archivers. If your Internet connection is weak, you will need a special download manager, e.g., Reget. It is a convenient and popular every-day HP (Hewlett-Packard) program.
