Printing from Preview does not bleed to edge of paper

Question

I am not sure if this is the right place to post, but it is is an issue with the OS, I think.
When I print from ipad or iphone, my printer has no problem bleeding the image and printing onto the entire page, L or XG size paper (I am in Asia currently).  However, when I print from preview, it does not work.  It always creates a border around the image.
I have added a custom size paper for the photo paper I am using and the printer settings show that the unprintable area is zero on all sides.
I also select "fill the paper" from the print settings and the preview on screen clearly shows that it is filling the entire paper.
Yet, when I print the document, there is always a small border around the entire image.
Anyone have any ideas how to fix this?  I can workaround it, but it would be great if it just worked from Preview.
Thanks in advance!

Answer 1

Well, my paper size is not listed, so I had to do a custom size.  So, I put in the exact size of the paper, which is KG size (Japan photo size) and is 102 x 152 mm.  I also have L size in there which is 89 x 127 mm.  Then, I put the non-printable area size as zero on all four sides.
Is it simply that my paper dimmensions are wrong?  I took it from the package and from wikipedia http://en.wikipedia.org/wiki/Photo_print_sizes
Perhaps I should use 100 x 150 for KG size?
