Just use the new PPD file for the new printer's set-up. You can still  
keep the old printer and make the new one your new default. So you  
can compare ...

There could be one cause: byte order (or is it bit order? I "once"  
had this in SunPC, a PC emulation running on SPARC based suns: intel  
is LSB first, the rest of the world is MSB first! The colour pictures  
looked psychedelically.) Imagine the scanner's output has an alpha  
channel. It could be misinterpreted as completely opaque and printed  
as deep black. Or such!

What is on the command line

	file <your TIFF file>

telling? You could also invoke

	sips -g all <your TIFF file>

Mit friedvollen Grüßen
