Just got an HP 6055 Envy Printer. Generally works well. For some reason I was able to do double sided printing a few weeks ago and now it's no longer working.
I did try to read as much as I could online on troubleshooting. I have made sure the Double Sided Printing button is checked off. Layout is checked off with Long edge binding. I have also gone into System preferences and Reset the printer. None of this works. Can someone help? This function was working a week ago.
Thanks
Lynn
