Digital BW, The Print

I need help - when I print (using generations enhanced ink with profiles on an epson 
1270), my monochrome and tinted prints ( RGB or Grayscale files), are previewing and 
printing with a very strong cyan (purple!) cast - should say color, as it is so strong. The 
monitor is calibrated - print looks good - then disaster! I have checked my driver settings 
- seem to correct; color management off etc.
Anyone had similar issues - found any solutions?
