For local hard drives you can use the variable "@fixed" to reference them. I dont find the policy that you are refering to. However, you can define a rule that stops people writing to "@fixed:\**\*".
For the printing, if you are refering to network printing then a NAC rule can be defined for this.If you go to policy "Security - Data Loss - Prevent leakage" you can copy this to your own rule module and modify it to suit your requirements. I haven't been able to test this.
