System 7.5: Error Installing Printer Software

We have a Power Macintosh 6100/60 and are getting the following error message when selecting Easy Install with the LaserWriter Select 300 disks:

"The selected disk has System 7 installed, the custom installation you have selected is only for disks where System 6 is installed. Please click Switch Disk to choose a different disk or insert a floppy disk".
You will only receive this error performing an Easy Install, Custom installs are unaffected. Any computer with System 7.1.2 or System 7.5 installed can have this problem.

This problem also occurs with the StyleWriter II installation on the Power Macintosh computers. Basically, the LaserWriter Select 300 and StyleWriter II Installer scripts are not aware of the Power Macintosh computers and new system software.

Install printer drivers from the system software disks rather than from the disks that accompanied the printer.

To install the additional TrueType fonts included with your printer, use the Custom Install on the printer software disks. You should only install fonts from these disks. Do not install the printer software from these disks.
