I am having the same problem with our WorkCentre 7125 machines.
When I print one picture per page it works fine, but when I print 2 pictures per page I just get a thin strip across the top and the rest of the page is blank.
I have used drivers 5.377.6.0 and the latest 5.404.8.0 and it is the same with both.
If it was fixed in 5.347.7.2 then why has it returned ? Can I download the older version anywhere ?
