Macbook Pro cant print duplex with HP Printer

[sandyh]

Since setting up my old HP Printer through HP Easy the duplex function is greyed out. Have tried to fix by following others who had similar issues but still have the problem. If I reinstall the original printer software then I can't get Wifi printing to work. Wifi printing did work before moving back to the UK. ?? HP Laser Jet 100 color MFP 175nw. Any help appreciated. Thanks

You might list what else you have tried, like:

Did you try manually configuring via the CUPS interface?

Oh, and what OS and what version of the HP drivers are you using?
