I tried installing CUPS, after following Qole's instructions for freeing up space, but unfortunately still ran out of room when attempting to install cups.
mkdir -p /media/mmc1/apt-archives/partial sudo mount -o bind /media/mmc1/apt-archives /debian/var/cache/apt/archives
I ended up having to uninstall Easy Debian and then reformatting the partition on which the image was located, as deleting the image did not free up space in the partition and the image installer stopped working. There may have been a more elegant solution, but there's a lot I don't know.
