I have a LaserJet Pro P1606dn printer. Is it compatible with Windows 10?
Yes, the printer is fully compatible with Windows 10. In fact, HP released the full driver package that can be downloaded from the official website. Use the link below, then click the package and the download should start automatically. Unplug the printer from PC and then start the installation. Follow the procedure and that's it.
