Enabled: SilentPrintingEnabled = 1
Disabled: SilentPrintingEnabled = 0
Description
Setting this policy to true enables silent printing, which immediately closes print preview window when opened and prints to the default printer with default options. If the default printer is 'Save as PDF', the file will be saved to the Downloads folder. Not setting this policy or setting this policy to false disables silent printing, which doesn't automatically close print preview window and requires the user to make a selection as usual.
