Printing with FZX

[boriel]

FZX es a bit special home made routine. You probably will have to make your own routine. The thing is that FZX uses non proportional font, and knowing when to wrap a word or to stop is tricky.
For the error message, perhaps you can "trap" it and call the ROM scroll yourself.

Consider joining the telegram channels, btw. We are a vibrant community and probably someone has already researched this!
