Command Line printing does not honor Registry Settings - Print as Image

The following command line prints a PDF successfully as Vector

acrord32.exe /n /s /t "filename.pdf" "printername"

however the Print as Image settings defined in the Registry at the following keys are being IGNORED

HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\DC\General\cPrintAsImage

with subkeys the drivernames that are currently set to 'Print as Image' are listed here.

Try printing something as Image manually to a Driver that is stopped and you will see how Acrobat maintains the entries.

HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\DC\AVGeneral

Value = iPAIRes

The Print as Image Resulution is defined here

When setting these Registry values manually and opening Acrobat manually, and doing a print (even without entering the Advanced Print options screen, the print is done correctly as a rasterized image

When printing from the command line, the Print as Image settings are simply Ignored! Why ?
Other Print settings from the Registry at HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\DC\AVGeneral are honored

Is it possible to print from the command line in 'Print as Image' Mode ?

thanks
