Digital BW, The Print

After setting a custom paper size in QTR, the print preview dialog shows the 
image correctly oriented to print the way I want (landscape on an 8.5 x 17 
sheet).  When I print, it prints across the width of the paper, cutting off most of 
the image (it's a panorama shot).   

If I switch the selected printer from QTR to Epson MK driver, it prints correctly 
(except that it's tinted instead of B&W).  What am I doing wrong?  Of course, I 
have a deadline for tomorrow for two prints for an exhibition.   Please help.

Thanks,

peter
