Apple Color LaserWriter 12/600 PS - Manual (Page 162)

Mac OS–based computer troubleshooting
The desktop printer icon has an X drawn through it.
The X indicates that the desktop printing software is turned off or the
LaserWriter 8 extension is not in the Extensions folder.
m You may have started the computer using a different startup disk or
temporarily turned off all the software extensions. When you restart the
computer as usual, the icons will return to normal.
m You may have removed the desktop printing software that created the
printer icons. If you meant to do so, you can drag the icons to the Trash or
to any folder outside the Extensions folder. If not, you can reinstall the
software as explained in Chapter 2 of this update.
m The driver for the desktop printing software is no longer in the Extensions
folder.
m The desktop printer icon is a duplicate of an active desktop printer.
The desktop printing software needs more memory on the computer.
If desktop printing needs more memory, try closing open windows and
quitting open programs. Each desktop printer that you use also requires
memory, so try reducing the number of desktop printer icons on your desktop
by dragging desktop printers you no longer need to the Trash. You can also
allocate more memory to the Desktop PrintMonitor. To allocate more
memory, open the Extensions folder in your System Folder and select the
Desktop PrintMonitor icon. Choose Get Info from the File menu and enter a
larger amount of memory in the Preferred Size box, then close the Get Info
box. To allocate more memory to a specific desktop printer, select the Desktop
printer icon. Choose Get Info from the File menu and enter a larger amount
of memory in the Preferred Size box, then close the Get Info box.
Apple Printer Utility can’t find an external hard disk.
You’ve attached an external hard disk to the printer. The Apple Printer Utility
can’t recognize an external hard disk if you turned the disk on after turning on
the printer.
Note: You must initialize the hard disk before you download fonts to it.
