Digital BW, The Print

What is the complete list of printers that are compatible with any of 
the Quadtone B&W printing systems that are out there? Usually, I've 
only seen Epson printers mentioned. Are there Quadtone B&W printing 
system made for Canon printers also? Other than through auction, 
where can I purchase any of these models? 

Thanks
Terry
