I have just spent 20 minutes trying to get an image to print in the correct size. I have a large-format printer and am trying to print a 10x16" image on Super B paper. GIMP keeps changing settings back to letter. I've checked the bug reports and this has been reported repeatedly but nothing seems to have been done about it. Now I have to find some other way of getting this image printed in the needed size. The software does a lot, but this is a very basic problem and appears to be a longstanding one.
