Yes, you can point a group to a printer. If you find yourseld moving printers around, you can always use CHGUSRPRF to fix that.
Bear in mind that some applications control the user's printer output as well. Check with the programmers to see if you need to change anything there.
On our system, everybody has an entry in a file with their printing defaults. The entries are used by all the report programs (the users are prompted to change them, or they can leave them the same, each time they run a report). This way, there's no guessing as to where the output goes. But that's an issue for the programmers.
Here's my record, for example:
[tt]
DFTUSR - USER ID........: F_LAPEYRE
DFTOTQ - OUTQ...........: PGMOUT
DFTCOP - COPIES.........: 1
DFTHJQ - HOLD ON JOBQ...: *NO
DFTHOQ - HOLD ON OUTQ...: *YES
DFTSAV - SAVE OUTPUT....: *NO
DFTNIT - SUBMIT TO NIGHT: *NO[/tt]
