For me LibreOffice prints perfectly duplex on the HP OfficeJet Pro 8500A Plus.
Can your follow the instructions of the sections "CUPS error_log", "Capturing print job data", and "Getting the data which would go to the printer" on https://wiki.ubuntu.com/DebuggingPrintingProblems. Can you also attach the file(s) which you tried to print? Please do this for all situations with problems (LibreOffice, evince, ...). Do not pack the obtained file together and do not compress them. Please attach them one by one. This will make it easier for the readers of this bug report to handle them. ** Changed in: hplip (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to hplip in Ubuntu. https://bugs.launchpad.net/bugs/1099143 Title: HP Officejet Pro 8600: Duplex printing doesn't work Status in LibreOffice Productivity Suite: New Status in Evince document viewer: New Status in HP Linux Imaging and Printing: New Status in “hplip” package in Ubuntu: Incomplete Bug description: I wanted to print a document in duplex mode. Different applications showed a different behaviour but none of them worked as they should: LibreOffice just didn't print in Duplex-mode. But I've chosen this mode. Evince, using the PDF produced with LO, printed the first "package", but the second not (in fact the printer produced an empty page, then printed one page, one empty page and printed the last one), the third "package" was printed in duplex mode, but not the fourth and so on .... The same did the HP-toolbox.
