Desktop printers cannot be disabled when the Finder is the current application, and thus the LaserWriter 8.x driver (which has 4-up printing capability) is not available. The important thing to note here is the behavior of GX Helper. Basically, GX Helper and its ability to disable desktop printing ONLY operates in the following situations:
* It can only disable desktop printing with applications that are not GX-aware. Since the Finder is GX-aware, desktop printers cannot be disabled.
* It only works with equivalent APPLE-brand printer drivers that are in the Extensions folder. For LaserWriter GX, it will use LaserWriter driver v7.2. LaserWriter 7.2 was the only version tested with GX Helper. LaserWriter driver 8.x and 8.xf seem to work with GX Helper, but they are not an Apple supported solution in the current revision. Also, any third-party printer drivers will NOT be seen by GX Helper.
