If you have presentations in Keynote 2 that contain some built-in themes that use transparency (such as Graph Paper), the presentation may not print to some network printers, such as the HP Color Laser Jet 4500. You won't see an error message onscreen, but your print job may suddenly disappear when you try to print.
This can happen with Keynote 2.0.1, HP Color Laser Jet 4500 (there may be other affected network printers), and Mac OS 10.3.6 through 10.3.9. This does not occur on Mac OS 10.4 Tiger.
To prevent this from happening, make sure that all objects in your presentation are set to 100-percent opacity.
