Use a laser printer and transfer paper.
quote…..

1. Get a Laser Printer. … Most laser printers print with iron, which is a stable and safe ceramic material.
2. Buy the Transfer Paper needed to print.
3. Print Your images from the laser printer on the decal paper and increase the contrast for best results. (Photoshop Works Best).
4. Cut out the images, and soak them in water.
5. Once the film separates apply to an already glazed surface and smooth the wrinkles out.
6. Fire to cone 04 or higher, and you have an image on ceramics! (Goes great in a bisque kiln).

…unquote.

I really should get my own kiln.
Then I can really play with glazing temps and the extra-runny (read pretty) glazes.
