How do disable double-sided printing on Envy 7640 on Mac system

[HeatherBOS]

I'm sorry this didn't work.  It should be more intuitive.  I've had this printer for years and never had this problem.  I don't know what happened but I can't turn it off.

@HeatherBOS, Welcome to HP Support Community!

Which application are you trying to print from?

Refer to the document HP Printers - How to Print on Both Sides of the Paper (Duplex) (Mac) and uncheck the duplex printing options wherever necessary.

When you set up a duplex printing job, the settings might carry over to the next print job. Additionally, some HP printers come with duplex printing set as the default. To change back to one-sided printing, turn off the duplex setting in the print window.

To preserve duplex or one-sided settings for future print jobs, complete the print job with the desired settings, click the Presets menu, select Save Current Settings as Preset, and then give the preset a name such as One-Sided Documents.

Hope this helps! Keep me posted.
