The difficulty in printing concerns the version of AppleWorks being run from the server. The ability to print from Applesoft indicates that the hardware is properly configured. AppleWorks 2.0 is not licensed for, nor designed for, running from an AppleShare server.
For a version of AppleWorks licensed and designed for running from a server, use AppleWorks version 2.1N. Be sure, in AppleShare Admin under the Apple II menu, to set the user's account to the desired printer. The alternative would be to run AppleWorks 2.0 from a local disk.
