I am very curious about your program. How do you plan to wrote it ?
Are you printing form Windows ? 
I mean I have seen a guy in this group that was printing from some
kind of a RIP processor but this was under Linux and personally I'm
not that good to use linux for every day tasks.
Among misalignment of jet's on bidirectional printing, a big issue on
windows printer drivers is that that windows is automatically adding
some dithering and anti aliasing "functions". Those "features" are
extremely unappropriated for this job.
