Applewriter II works correctly on the Apple IIGS, except that you cannot
print using the built-in ports to a standard RS-232 serial printer. You can,
however, use the ports to print to a Laserwriter or an Imagewriter II over
Appletalk. You can also print to either a parallel or serial printer by
simply installing a compatible interface card, such as a Super Serial or
Parallel card, into one of the Apple IIGS's slots.
To print to the Laserwriter or an Imagewriter II over Appletalk, you must
first use the Chooser that comes with the Apple IIGS system disk. Choose the
Appletalk printer that you would like to print your documents on, and then
exit the program. When you are in Applewriter II, make sure that the last
line of your document contains a form feed command. To do this, just type in
the following as the last line in your document:
Control-V Control-L Control-V
This command will force the Appletalk Imagewriter and Laserwriter to eject
the last page of the document.

albeit with AppleWorks, see the article in this Library called "Apple IIGS:
Printing to the LaserWriter from AppleWorks."
