Sharp AR-285 and AR-507: Several corroborating reports suggest that the PPD for these models is also faulty under Mac OS X 10.2.2. A similar problem was reported yesterday with the Xerox PPD, and other reader reports suggest the same difficulity with Kyocera Mita PPDs. Konica IP-511 V1.1.1: Ben Stanfield reports that any application will crash before bringing up the print dialog screen when using the Konica PPD. A short list of the most widely afflicted models: PPD (Postscript Printer Description) components seem to be causing significant problems. Incompatible Printers A number of printers, particularly models from Samsung, are having difficulty printing from systems running Mac OS X 10.2.2. Similarly, removing the supplied HP Communications software component, and instead using the open-source gimp-print 4.2.4-pre1 drivers may allow proper function without system slow-down for some Hewlett Packard printers. The company's workaround suggested removing the HP ScanJet Manager from the "Login Items" pane of System Preferences, then using the scanner through a third-party utility or the included PrecisionScan Pro software. In Mac OS X 10.2.1, the HP ScanJet Manager software component also severely drained processor cycles, in some cases using up to 90 percent of the system's resources and causing dramatic system slow-down. Killing the process "HP Communications" - accomplished by using the "Quit Process" command under the File menu in Process Manager - alleviates system sluggishness, but in turn disallows printer functionality. Process Manager displays gradually increasing processor usage from the application, rising upwards of 60 percent in most instances. Most reports indicate that the problem takes hold after a few hours of normal operation, and result in slower menu access, increased application launch times, and delayed window drawing in the Finder. HP Communications causes system slowdown Hewlett Packard's "HP Communications (version 4.6.3)" component is the culprit behind at least some of the reports detailing overall system sluggishness after applying the Mac OS X 10.2.2 update.
