Workaround

If your existing Printer Protection Rules in your DLP Policy have specific Classifications mentioned in the Condition or exceptions, printer protection doesn't work on Adobe Acrobat Reader 64-bit. In such cases, implement the workaround below:

Log on to the ePO console.
Go to the Policy Catalog.
Choose Data Loss Prevention.
Edit the DLP Policy.
Create a Printer Protection Rule specifically for Adobe Acrobat Reader 64-bit. Include the process name Acrobat.exe.
On the Printer Protection Rule page:
1. Enter a Rule Name.
2. Set the State to Enabled.
3. Set the Severity according to your requirement.
4. On the Condition tab:
  1. Select Any Data for the Classification and End-User of your choice.
  2. Click the three dots next to Applications and click New Item.
  3. Enter the Application Template name and leave the rest to its default.
  4. Under the Available Properties section, select the Property Original Executable File Name.
  5. Set the Value as Acrobat.exe.
  6. Click Save.
  7. Select the Application Template name that was saved in the previous step and click OK.
5. On the Reaction tab, make the changes below:
  1. Set the Action to Block.
  2. Click the three dots next to the User Notification and select a notification from the list.
  3. Click OK.
  4. Select the Report Incident checkbox.
  5. Select the Store original file as evidence, if you want to store evidence files.
  6. Click Save and Close.
Apply the pending changes to the policy and enforce it to the computers. Printer Protection blocks all Print operations from the Adobe Acrobat Reader 64-bit.
