This reply comes late, but for those who might search the internet desperat ely in the future. The solution is easy. HP printers with an ethernet port come preset with TCP/IP values. In the case of the HP 2000DN or in my case
2100TN, a person needs to hold the Power and Reset button on printer at sam e time for 5 seconds to print out the configuration of the printer.
HP printers are typically set to Default Gateway 192.168.0.1 ASUS routers like the RT-AC66U and RT-AC68U are set to 192.168.1.1
A network cannot mix gateways, they all must agree by the third number valu e set, 1 or 0. Since the HP printer is fixed with 192.168.0.1, the ASUS rou ter (or any other router for that fact) must be set to match.
From your administrator interface on the router, select LAN > Configure you r LAN. Change the value from 192.168.1.1 to 192.168.0.1 and click Apply. Th e router will reset and the DHCP will issue not IP values network wide. You r ethernet computers will roll over after a few seconds. Wireless devices w ill have to be manually reconnected to the LAN, which is simply a matter of selecting the connection source again.
Download and installed the HP wizard for Windows to connect your computer t o the Ethernet connected printer:

or search for hp piw.exe.
If you can see the printer by this software, you know it is connected. Then proceed to download the PCL6 drivers and install. For the Mac,
