Symptom
A shared printer is not available after updating to Mac OS X 10.2.2, or to Mac OS X 10.2.3 using the Mac OS X 10.2.3 Combo updater, or to Mac OS X 10.2.4 using the Mac OS X 10.2.4 Combo updater.
Note: If you are a software developer or advanced user who has customized the cupsd.conf file in any other way, those changes are also lost when this file is replaced during the update.
