The Dream:
While booted in OS X go to Apple Menu > System Preferences > Startup Disk. Select the icon for the OS X Volume and then click Restart.
After the Restart go to Applications > Utilities > Disk Utility.
Launch Disk Utility.
Select your HDD (manufacturer ID) in sidebar.
Select First Aid tab.
Click on Repair Disk Permissions.
With a little bit of luck this will take care of your printer woes. If not, you can go to the website of the printer manufacturer and download the latest version of the printer software.
For good measure, especially since you have difficulties with your optical drive and can't boot from the install disk, shut down the computer and try
starting up in Safe Mode. Here's how:
1. Be sure the computer is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, press and hold the Shift key.
Tip: The Shift key should be held as soon as possible after the startup tone but not before.
4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
