HP m506 disabling duplex printing

[dactyls]

Hi all,  I know it is a driver functionality that is overriding printer, windows, and software requests to print one sided only but I'm unsure of where to finish changing the driver setting to print one sided.

For my example we are printing a multi-page workbook from excel, windows is set to single sided printing on printer preferences.  Excel is set to single sided printing, and the printer configuration is set to single sided but the workbook still prints two sided.  

Would anyone be able to assist with where to change the driver setting that is overriding everything else?

Thanks!

Assuming that it is a driver fault (as alluded to by at least one of the above links), it may be worth changing the printer's own default setting for Duplex from On to Off.

Do this via the Embedded Web Server on the printer; this example is for a LJ Pro 400 Colour MFP M475dn, but I'd guess that the EWS on your model looks similar:
