Question: after update hp officejet 8600 only prints duplex, help
I recently update my iMac to iOS 10.13.1 now my printer HP officejet pro 8600 will only print in duplex mode. (Both front and back) Used to have a button that I could uncheck when I did not want duplex printing. That button is no longer there after updating. Any help is appreciated.
iMac (27-inch Mid 2011), iOS 10.3.1
