Hi Tariq,
We have a group policy in place that adds printers and sets the default. However, that group policy gets overridden at a first time login by the Adobe PDF printer being automatically forced to be the default. That only happens once and every subsequent login gets the appropriate default printer as dictated by group policy.
If there's no preference to tweak then would this be considered a bug? I run computer Labs that are frozen with Deep Freeze, so every student is logging in for their first time, which means that they will always get the wrong default printer unless I remove the Adobe PDF printer altogether. So that's what I am doing for the time being.
Thanks!
