All of the x3270 emulators support printer sessions.
A printer session is a copy of pr3287 running on your workstation, that the host can send print jobs to. It is specifically tied to your interactive login session, so other users cannot access it.
Printer sessions are controlled by the printerLu resource. If this resource is defined, the emulator will start up the session as soon as the host connection is established. Your host, of course, needs to be explicitly configured to support printer sessions.
There are also a number of other resources that control the printer session.
