This is a potential issue with the PowerBook G3 Series (Bronze keyboard) running Mac OS 8.6 or 9.0, when a printer is connected using a USB to Parallel adapter cable, sometimes referred to as a dongle. This issue is being investigated. If you encounter this issue here are some ways to work around it:
- If the printer has true USB support, use a native USB A-to-B cable instead of an adapter cable.
- Connect the printer cable to the PowerBook only when intending to print.
- If the printer cable remains connected during a sleep/wake cycle, restart the computer after it wakes from sleep prior to printing.
