Hi Steve,

What it looks like to  me is the microweave pattern.   It this at the end of the
image area?  I think the problem is that the printer didn't finish printing the
end of the image.   It takes a little while to process the white margin at the
end of a page and the final print data very often doesn't get sent to the printer
until after the margin is processed.   So I'm guessing that maybe you 
manually ejected the print prematurely.
