I have to use a OS 9 classic application that has to print to a HP LJ 1320 USB. With OS X 10.3 no problem. After Upgrade to 10.4 printing brings up error -199, no printing occurs. Please help, thank you.
Try deleting print-related preferences in System Folder "9" /Preferences.
Then while in the Classic APP, go to Chooser and set up the printer.
Is there an OS 9 version HP Laserjet driver for this model? you may get the best results with that.
