There’s an easily solved problem with Apple LaserWriters (12/640 & 16/600). The problem (assuming that you have properly connected your BeOS machine to the LaserWriters in the same AppleTalk zone via ethernet & checked the „Enable AppleTalk“ box in the Networking preferences) lies in the name of the printer. The BeOS uses „/ in the pathnames to the printer, ergo the name of the printer cannot contain a „/. You will have to use the Apple LaserWriter utility software to change the name of the printer to something a little more amicable („Fishy LaserWriter“ works well for our 12/640).
