Print quality not saved.

[forum]

Running Irfanview 64 bit on Win 10. Have only one printer, Kodak Hero 7.1. Have set this as default printer in W10, and have set the print quality to highest. All other programs use this default quality unless I change it, but my Irfanview will not use the default setting but rather uses the lowest qualiity print. All other programs (Word, PowerPoint, Publisher, Firefox, etc.) use the default printer setting just fine. I have told the installation to put the ini file in the same folder as Irfanview (i.e. Programs/Irfanview) and I see it there. I have checked that the attributes of the i_view64.ini file are not "read only" (tick box is empty). I am at my wits end on what to do. Of course if I change the printer property each time I go to print it will go to the high quality print, but it will not remember that setting no matter what I try. Any suggestions would be very welcome as to how to fix this frustrating issue.
