I had a Prowriter printer when I bought my first Mac, and, knowing
that the Mac Imagewriter was a slightly reworked Prowriter, and only
having a parallel port on the printer, I wrote an Imagewriter emulator
on my Z-80 S-100 computer which translated the few different graphic
commands and sent them to the Prowriter parallel port.  I had to
keep track of graphic vs. non-graphic mode, to prevent modifying
graphic data that looked like commands.  Gave me a big print
buffer, too.
