It is possible to print to an Apple Color StyleWriter 1500 or 2500 from a Power Macintosh 8600 or 9600 via the printer drivers and OS that shipped with the computers, but you will be unable to use ColorSync until you install the ColorSync profiles for these printers.
If you select ColorSync (a Color option in the Print dialog), you will receive the error message: "There are no profiles in the ColorSync profiles folder for 'Color SW 1500/2500.' Please install the profiles using the installer diskettes."
Workarounds
1. Use the Halftoning options instead of ColorSync.
2. Follow the recommendations given in the error message to install the profiles via the Color StyleWriter Installation disks that shipped with your printer or which can be obtained from Apple Software Updates sites.
3. Obtain and install Mac OS 7.6.1. Mac OS 7.6.1 (and 7.6) have the proper ColorSync profiles for the Color StyleWriter 1500 and 2500.
