Great!

After doing that, I can now see those 4 lines filled in correctly, and the

Good, so you are getting content into your file now.
So you could check that the linux print file has the same PJL lines as the
Windows print file, and in the same logical positions? (after/before
something specific)
And nothing else missing in the linux file that is in the Windows one?

The problem doesn't appear to be the authorization, but I'm not really sure

Maybe not the right driver? Maybe the printer just does not understand the
particular format CUPS is producing for it?

How about taking a Windows printjob, stripping out the PJL lines, then
passing that printjob through your filters to see if the output can be
printed?
Then at least you will know that an original printjob with those particular
lines automatically added to it by your filters will work.
What other differences there might be you would probably be best served by
examining the Windows printjob more thoroughly first to see if you missed
anything.

p.s. On your blog, "Step 2: Add to line mimefx.convs" should be "Step 2:

OK, I will make the grammar correction.
