I have an Intel NUC5PPYH and I cannot have a flawless duplex printing. I am currently running Win 10 Pro 64 bit built 1703. Whenever I try to print a 2-page document, created on MS Office 2010 Word, I end up with a sheet of paper where the front page print does not 100% overlap the print on the back page. Lets say that the front page has 32 lines of words typed and the back has also 32 lines of words typed. In an ideal situation, the front print (i.e the first 32 lines) should overlap the next 32 lines. In my case, printing of the front page starts lower than usual (4 lines lower to be precise) whereas the back page printing starts normally on the top of the page, thus I am having a sheet of paper where if you place it under any light, you could see that the 2 printings (front & back) do not overlap. Sorry for my english, this is the best way I can describe the problem, treat the document in question as an x-ray and place it under normal everyday lighting. Every paper has some degree of transparency.
I am using the default settings in MS Word, margins, spaces etc are used as is.
I was facing the same problem when running Win 10 Pro 64 bit built 1607. I updated to built 1703 hoping for a fix. My printer was an HP DeskJet Ink Advantage 4535 AiO, which had automatic 2-sided printing and was connected to my NUC through usb cable. I had to return it to the store. I have also used a Samsung Multifunction Printer Xpress M2885FW which also had automatic 2-sided printing, connect it through usb, the problem still persists.
Moved my NUC to a place where another HP printer which also had automatic 2-sided printing, unfortunately, problem persists.
I have also converted the aforementioned 2-sided file to a PDF, still facing duplex error.
I have also uninstalled Win 10 Pro and installed Win 7 Ultimate 64 bit. I didn't solved the problem.
While running built 1607 (Win 10 Pro 64 bit) I also used MS Office 2007 and 2016 Pro, faulty duplex printing continued. I am currently on built 1703 with MS Office 2016 Pro.
Purchased heavier paper (120gr instead of 80gr), thinking that it may be a roller issue (or whatever mechanism is used to grab the paper), didn't solved it either.
I have also installed Libre Office and used it for printing only documents that were created in MS Office and magically the problem was solved! Used Libre to open other files created under MS Office, and printing was fine.
Lastly I have also emailed the above document to a couple of friends that I knew they had printers with automatic 2-sided printing, asked them to not change any Office parameter and print it. 2-sided printing was fine.
Looking forward to a solution.
