To get a ProDOS application to print correctly, you need to run the "Chooser II" program, which is in the AppleTalk folder on Apple II Workstation disk. This program allows you to select a printer.
NOTE: If the printer selected is a LaserWriter, the ImageWriter emulator is downloaded immediately. "Chooser II" can run from either the server or the work-station. Ensure that the application is printing to slot 7. If printing to a LaserWriter, set up the program for printing to an ImageWriter.
