have you set bg->setTile(true) ?

hm, you could save the tiles as separate files, then you'd only need an
Image the size of a single tile. There is hopefully some smart image
processing library that can create on large file from a number of small
ones?
However, does that even help with printing? I mean can the printing APIs
deal with not getting the whole image at once?

yup, FBO... *runs and hides* ;)
