I have just "unstuffed" the minimal printer software for my StyleWriter printer, but I am having problems using it. The file has a generic document icon instead of a printer icon, and although I dragged the file to the System folder, it did not show up in the Chooser.

The Minimal Software for the Color StyleWriter 4100/4400/6500 printers is shipped as a self-expanding archive file (.sea). In some cases, after you double-click the .sea file, unstuffing is not completely successful: The unstuffed file ("CSW 6000 Series" or "CSW 4000 series") appears with a generic document icon (a rectangle with a folded corner) instead of a printer icon, and the Macintosh may not recognize the file as a printer driver.

To correct the icon, simply drag the file to or from the Desktop. The icon should change to an icon of a StyleWriter printer. (In rare instances you may have to rebuild the desktop to correct the icon. To rebuild the desktop, restart the computer while holding down the command and option keys. When the desktop appears, you will be asked if you want to rebuild the desktop. Click OK.)

Once the icon has been corrected (looks like a printer), you can drag it to the System Folder. You should be prompted that the file is an extension and needs to be moved to the extensions folder. Click OK. The file should show up in the Chooser.
