Raphael, I am having the exact same problem. I am running RedHat EL4 linux and when using ImageMagick it gives an "Unable to print X image." error message, and it does not print anything. The exact same hardware ran fine with no adjustments under RH EL3. The ImageMagick-display is version 6.0.7. Do you know what the problem is? How did you fix your problem? Many thanks, Wayne Channell
