I was travelling last week in the US, and noticed that Photoshop was taking a very very long time to open or create files - 2 or 3 minutes in most cases. After some trouble-shooting, I eventually realised that it was because my default printer was a network printer. After I switched my default printer to a local printer, normal service was restored.
[Side note: I usually use FinePrint as my default printer – this is a software printer that allows you to manipulate the output of your printing sessions prior to sending to a physical printer. Highly recommended.]
