This is an excellent idea. Since all printer drivers are in user space, I would really like to see this turned into: **All LSB certified printer drivers will work on all LSB certified distros**. 

What do you think? Instead of creating a separate certification program, we should use the existing brand and certification program that is well suited for this. The planned tests can certainly become part of LSB printer driver certification test suite. Similarly we should be developing tests for distros from printing point of view.

Thanks,
