True, but I am not quite there yet. My first attempt to print to a pdf file 
yielded just the upper left hand corner of the image in the output pdf file, 
about 1/8 of the total. My attempt to preview the output yielded a blank 
white page in the preview. 

My test image is a photo of 901884 bytes. 

Probably there is a density vs. papersize problem but I can't find settings 
for these in the print routine. Well, there is  papersize option but it is 
grayed out.
