Digital BW, The Print

Guys,

I need clarification regarding the maximum dpi of a file the Epson 
printer uses. Is it correct to say that the printer only uses up to 
240dpi files to output to 1400dpi, etc. ?  Or should that be that the 
printer driver only uses 240dpi?  Is the printer capable of accepting 
higher dpi files with a different driver?  I recall seeing some 
discussion of this and may have it confused or am not stating it 
clearly. 

In the Pieziography manual it says: "Although images print with 
clarity at 240dpi, there will be a remarkable increase in detail if 
you can obtain your images at 720 dpi and higher."  I don't know if 
that means the detail is gained at the larger print sizes with higher 
rez scans which is the conventional way of expressing it or that the 
piezo driver gets the printer to use more of the scanned dpi above 
240 - which I doubt it does.

thanks,

AZ
