If you want to print a color photo of a document WITHOUT a white border...

...make sure your scan of the document will scale to 8.5x11". Open a new Google Doc and choose File>Page Setup and then enter "0" for all four margins. Go back to the Google Doc and choose Insert>Image>Upload from Computer. This will insert your document (photo) at the upper LH of the document, and you can then resize it to fill the document if it doesn't do that on its own. Print (make sure your printer's advanced settings are for its equivalent of "no border") and voila!

My mom sent me a color photo of her BC because we are having mail delay issues here and the color photocopy she sent still hasn't arrived. Every time I printed it, either as a photo or pdf, I got a stupid white border. So above is how I figure out to fix it (without fancy software or cropping skillz). You're welcome. :)
