To make a booklet, printed both side of the sheet in landscape is not possiblel if the paper is custom size, like one half of a legal size-- 7" x 8.5". Even the listed paper size Statement 5.5x 8.5 will not print dupex, either portait or landscape. My office jet 8600 would print statements duplex portrait. The 8720 will not. I am very disappointed by this limitation of the printer that is supposedly newer, improved. Is there a solution other than having to run the odd size pages first and then run the even side and pray that they will feed properly?
Thanks for engaging in the HP Forums! I see by your post that you are experiencing issues while doing 2-sided printing on your Officejet 8720 printer. I will certainly do my best to help you 🙂
I understand that the printer is not doing duplex printing in landscape mode with the custom paper size. I have not tried this myself, but ideally, it should work. Please let me know the following details:
1) Can the printer print 2-sided document in landscape mode while using a regular paper size like A4?
2) If you use the portrait mode, will it make a proper 2-sided document with the custom paper size?
3) Also, try a different customer paper size and check.

there is no problem doing duplex printing on letter or legal size paper. I tried both landscape and portait for the custom size which is 7" x 8.5" (half a legal) which got the message that it would not work and wanted to rescale for letter size. I tried the same with the listed "statement" size paper, which is 5.5 x 8.5. I tried you suggestion to reset the printer but the form on my Mac did not spresent an empty printer space. As well, I was nervous about getting that process screwed up. At 92 years of age I am cautious about making system changes.OK? I appreciate you dealing with this problem. Incidentaly, I did try the two pass throughs, first the odd pages followed by the even. With 12 pages I worked fine, even when the ink on the graphics was still a bit wet, which I was concerned about giving a pro blem with feeding the second pass through. But, it is not as good a solution if one is going to produce multiple copies of a booklet.
