The PrintNightmare threat and Lasernet service

Authors list


There have been some recent published recommendations from Microsoft regarding the 'PrintNightmare' threat. This involves a Windows Print Spooler remote code execution vulnerability.

Multiple components of Lasernet (beyond just the physical printing of documents) rely on the Print Spooler Service to be able to function successfully and so deactivating the Spooler Service means that the Lasernet server becomes unusable. If users deactivate the LPD service, the Lasernet server will not receive any jobs (from AS400 for example).

In summary, the Lasernet service depends on the Print Spooler Service to function, so we recommend that it is not deactivated on the Lasernet server.
