I am developing a Mac Plugin PDE driver based on MacOSX sample PDE and I met a strange bug about printer preset. In printer dialogue, when I swith to my PDE UI, I change some settings(such as jobtype, userid), and then save the settings as a custom preset(clicking [preset] button and select [save as a new preset] in printer dialog). The custom preset can take affect, but when I switch preset from custom preset to default(standard), the setting in my PDE can`t return to the default state. It is still the custom setting that I just set. #Other settings except PDE can return their settings to default when swith preset from custom preset to default(standard) setting. Anybody know the reason? I will be appreciate.
