Programming a printer driver (ARRG)

[Henrik Klagges]

Hi,
I just got a brand-new 5000 color sublimation printer into my office.
Right now, it only supports screen captures, via a digitizer. However,
I would like to write a driver ...
Any one any idea how to do that ??
   - communicating with the parallel port
   - reading iris.rgb-files and uncompressing their encoding
   - programming the Hitachi 5000

Thanks !
