Powerbook G4. Computer doesn't recognise any printer, does not pick up the printers in system in 'add' printer. Anyone hae any idea how to 'reactivate'. When downloading printer drivers (specifically for Lexmark z615 home printer, inkjet) constantly crashes out at final hurdle. Usually and easily recignises standard printers from printer from 'libary', 'receipts' and then just picks up from there on detecting new or usual printer. These files say fro lexmark are there still, but even if you double click these, get same crash pattern. Never had this before so looking for solutions. Thanks. Gregg
