Problems Unique to the Macintosh 169
Troubleshooting
Jagged Text/Graphics, or Banded Gradations
■ Ensure your application supports Quick Draw.
If you are using a PostScript-compatible application, printed text and lines may appear
jagged and gradations may appear banded. As i850 is not a PostScript printer but a
Quick Draw printer, use an application compatible with Quick Draw for printing.
