Digital BW, The Print

I am using the latest QTR version (f, for Win XP)and am very happy 
with the prints.  What I have a question about is when I use QTR to 
drive my Epson 2200 I frequently (not always) will have the printer 
pass through the entire sheet of paper (loading paper one at a time, 
usually letter size).  Of course then the paper light flashes since 
the printer is out of paper, I guess it expects a second sheet to be 
there. If I just put the paper back and press the paper light it 
will print fine.  I do not understand why the printer wants to pass 
through a sheet before starting to print. (usual settings so far are 
1440 super, "better" speed, "ordered" dither, Centered image). 
Settings quirk?  Anyone else notice this?  Thanks.  Robert
