I am using HP LaserJet Professional P1606dn. I just started using HP ePrint, and I don't know how print on both sides of the paper using the HP ePrint. Please help me.
However, there is currently one way to duplex print using ePrint - if you're using ePrint from a computer (not a mobile device), you can install the ePrint Print Mobile Driver. This allows you to duplex print (printing on both sides of the page) using ePrint. Keep in mind that it is only possible when printing from a computer.
