HP Officejet Pro 8600 Plus prints web pages very small from IOS 11

We have an HP Officejet Pro 8600 Plus which has been printing from our IOS devices perfectly well for many years. However, since upgrading to IOS 11 web pages print as a tiny image (3x5") at the top left on the page (although I suppose it does save loads of ink!). Interestingly PDF's print without any problem, the problem seems to be limited to printing from web pages. Any of the older iPhones or iPads, which cannot be upgraded to IOS 11, continue to print without any problems. Here is an example showing the IOS 11 printing on the left and IOS10 printing on the right.

 

I'm pleased to report that I've found a solution. Find the IP address of your printer (by pressing the network icon on the touch screen on the printer) and use a web browser to connect to the IP address shown.

Switch to the Network tab and select "Network Protocol" on the left hand side under General. Change the setting to "Enable IPV4 only", click the "Apply" button.

Now, restart the printer (I unplugged mine) and restart your IOS devices. Once you have done this you should find that you can once again print web pages at full size!

It's clearly a bug in IOS 11 with IPV6 (as IOS 10 works just fine). Come on Apple get it sorted! It's been months now and there are thousands of people reporting the same problem on the Apple and HP forums. As normal both companies are blaming each other and sending people off to perform a load of useless tests rather than admitting to there being a problem in IOS 11.

Let me know if this fixes it for you too.
