Installing the new CR Designer should not affect printing from older Sage.
The problem you're referencing is the run-time print engine only, which is installed with v2018.
If a machine (server / workstation) has the new run-time version, it needs the updated config file to be able to print from an older version.
If a machine (server / workstation) does not have the new run-time version, the updated config file will break printing from an older version.
(Where the config file is placed to enable it for a machine differs from Standard to Advanced / Premium).
