Printer Repair Questions? Ask IT Technicians for Answers ASAP
Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I think you might have a problem with drivers, and their being properly installed.
Also, to print duplex from MS Word may perhaps require that not only the exact proper driver for you printer model, be installed, and used, but also that the driver settings be set for duplex (or '2-sided') printing, as well as the print settings in MS Word. MS Word may not be overriding the driver's settings, as opposed to the other programs, and the driver's settings prevailing, with MS Word they come out 1-sided (as the driver is no doubt set... or if not an exactly right match of a driver, its settings too may be ineffective at directing the printer to use duplex mode.)
If you wish I can give you instructions as to how to uninstall, restart, and reinstall the printer's proper drivers.
