Your imagetops filter still reports the error
Unable to open image file for printing!
That leads me to the suspicion that your imagetops filter does not support jpeg because the build did not find the jpeg library.

Please execute the command
ldd /usr/lib/cups/filter/imagetops

The output should look like (don't bother on the "lib64" here):
