This is an advanced question for Acrobat DC...
We are trying to update every computer on our network with the correct registry entry to make their printer dialog default (atleast the first time, unless they change it) to "Print in Grayscale" = Yes
Location HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\DC\AVGeneral
The research I've done says that the registry key: iDestProfileSelector is the entry
I have even confirmed that when I print using either option and close the application, the value of iDestProfileSelector does change to these values. But if I manually change the entry via Regedit, after launching Acrobat DC Pro (I don't have Reader to test) and open the print dialog, it doesn't reflect the change to "Print in Grayscale". I've tried toggling back and forth with the value, and I've even gone so far as to reboot between registry changes. I can't seem to get "Print in Grayscale" to activate.
Is there another registry entry that needs changed as well? We'd really like to get help with this if we can.
Thank you, that was the documentation we were trying to follow, it lacks any information on forcing the application to print in grayscale. The only print-dialog option it has documented is bPrintSaveToner
