There's couple of values on the datablock that need to be set to make it a print brick.
hasPrint = 1;
printAspectRatio = ###;
An example of printAspectRatio, for 2x2 plate print brick, it would show as:
printAspectRatio = "2x2f";
And for the 2x2 ramp print brick:
printAspectRatio = "2x2r";
And for the 1x4x4 print brick:
printAspectRatio = "1x1";
1x1 without the f is actually 0.5x0.6, so a quality 1x1 print would be 512x614
Where if you add the f, it's 0.5x0.5, so it would be a square, 512x512
Ramps seem to be a 1:1 ratio as well.
Seeing how you have a 2x32 flat print brick, you would put :
printAspectRatio = "2x32f";
