Digital BW, The Print

Thank you very much Roy for providing us with an affordable substitute 
for Imageprint, I really like BO prints but this should  be a great 
alternative.  I immediately downloaded the files and am now trying to 
figure out how to make it work.  I have the Print-2200.bat file on my 
desktop as well as the gray scale tiff file that was provided.  I gather 
that one must drag the tiff file on top of the bat file and then some 
sort of miracle happens, but not on my computer.   Unfortunately my 
degree in computer science expired about  30 years ago.
I would like to request that someone more familiar with this process 
provide us with a detailed step by step process.   I imagine others 
would also find this useful.
Thanks in advance,
Mike
