I have an HP LaserJet Professional P1606dn, which has been great. It prints double-sided (duplex) — that’s the ‘d’ in P1606dn — and it connects to the network — that’s the ‘n’ allowing Jane to print wirelessly from her laptop.
But today… for some reason my P1606dn stopped printing double-sided. The option was still there in the printer properties—on the Device Settings tab, under Duplex Mode both “Allow Automatic Duplexing” and “Allow Manual Duplexing” were both ticked.
I tried changing various settings but nothing seemed to fix it. I checked if the driver had been updated. I rebooted the PC. Again, no improvement.
How I fixed it
I was actually in the process of trying to downloading the HP Smart Install software when I stumbled upon the answer.
If you have this printer, you’ll know that you can also connect to a configuration screen via the network. All you need is the printer’s IP address. Mine is at 192.168.1.73 on my local area network.
Tip: To find your printer’s IP address, press and hold the button with an icon of a sheet of paper with a down arrow on it. This will print the “Self Test / Device Configuration” sheet which shows under “Network information” the “IPv4 Address”.
Next, enter that IP address in a web browser address bar and hit enter to take you to the HP LaserJet Professional P1606dn network settings page.
Well, lo and behold, under the Settings tab there is a section called Paper Handling, and the Duplex option was set to Off. Changing it back to On fixed things for me.
At least, it did for the first document. I then discovered that (again for another mysterious reason) the next document’s paper settings were blank. Setting it to A4 restored the option to print double-sided.
So, in summary:
- Check settings (Control Panel > Devices and Printers > Right-click the printer and select Printer Properties > Device Settings tab).
- Connect to the printer settings via the network.
- Make sure the print dialog shows the correct paper size.
At least, that’s what fixed it for me.

I’ve come across the same issue today, but this time I’m not connected to a network, the printer is connected via USB.
To resolve this — I had a couple of Word documents that would only offer the ability to print duplex (double-sided) manually — I changed the page size to anything and then back to A4 and then made sure the margins were set to normal or wide, as I noticed that the document margins were oddly small.

Following kind feedback from a visitor, I have added information about how to find your printer’s IP address and then use that IP address in a web browser to access the printer’s network settings.
