If the Print dialog takes a longer time than expected to appear in Mac OS X 10.4 or 10.4.1 after choosing Print from an application's File menu or pressing Command-P, update to Mac OS X 10.4.2 or later.
This issue can occur after upgrading to Mac OS X 10.4 Tiger.
If you're not ready to update to Mac OS X 10.4.2 or later, you can reset the printing system as a workaround.
Note: It's normal for the Print dialog to take a little longer to appear the first time you try to print after restarting the computer (even with Mac OS X 10.4.2 or later), but it should appear more quickly the next time you print. In this situation, do not reset the printing system.
