Steps to reproduce the problem:
No ability to set print margins via GPO / GPP (registry)/ default preferences file. Desired for web-based ERP and core business applications can print as desired.

What is the expected behavior?
Desired to set either via
a) Group Policy via ADMX (allow user to override/update/change)
b) Group Preference via registry key or ini file (allow user to override/update/change)

What went wrong?
No options present.

Did this work before? N/A

Frustrating having to manually set margins for every user on every computer. This feature would ease deployment time in an office utilizing Active Directory.
