Yes you can. Create a DGM (exact data) with the printer in it, then create your rule with what you want to detect ( some data AND DGM ) then block it. If you don't know how to create and use the Exact Data, support can walk you through it.

HI, DHaag

DGM tested but is not compatible with Endpoint Block and Notify. So how could block?

thanks

DHaag, I tested here and get the following message error:

Marked EDM, IDM, and/or DGM rules will not trigger Endpoint Prevent: Block and Endpoint Prevent: Notify response rules. For the policy to exhibit correct behavior, you may either modify the marked detection rule(s) or the marked response rule(s). 

sorry, typo'd DGM should have been DCM. From the manual:

Endpoint Block and Endpoint Notify are applicable to
all Endpoint Prevent detection policies that are performed on the endpoint
computer. For example, Email/STMP, HTTP/HTTPS, CD/DVD, FTP, Print/Fax,
andUSBmonitoring all use Endpoint Block or EndpointNotify rules.
