Digital BW, The Print

I have been learning the workflow suggested by Clayton Jones for BO 
printing on my 1280, and discovered that the 21-Step+.jpg dated 
2/19/2003 (Paul Roark's Enhanced 21 Step Wedge) image in the files 
section for this group has a has a non-linear transfer function.
I straightened it out, and got better separation in the blacks.

This is the first time that I discovered where the transfer function is 
(thanks Clayton).

This curve may affect your results if you print it without looking at 
the transfer function in Photoshop under File>Print with 
Preview>Output>Transfer.

My question is -- does the transfer function apply if one just does a 
Print, rather than a print with preview?
