If you experience a real slowdown when using latest Adobe Photoshop or Illustrator (CS3 at the time of writing) when you open files or create new documents within the program, then you should check your system printer settings. Most definitely your default printer is offline or disconnected. Just make sure that your default printer is online (and try to avoid having invalid printers listed as well).
The slowness is caused by Photoshop/Illustrator trying to access the printer and until this request times out your Photoshop/Illustrator comes to a stop.
