AFAIK, there's a difference between AppleTalk to a
laser printer and running software off a LocalTalk
network with the IIGS logged onto a Mac.  The former
only takes a toll on interrupts when printing to the
printer.  The latter is the one that causes problems
since the IIGS is expected to "keep an eye" out
for data from the Mac.

So unless you were using Express to print to parallel
in the background, it does not matter because the
IIGS does not normally do background printing.  As
such, taking a toll or not taking a toll on interrupts
during printing does not matter.  You can't use the
IIGS at that time one way or the other.

In fact, if you only set up a network printer, you could
delete many of the AppleTalk files on the IIGS setup
if I remember correctly.
