FS#617 - Investigate Mitsubishi CP-M1E

just announced. 12s/print, 300dpi, "new engine", and 800 prints/roll.

Interestingly, they provide an ARM driver targeting Raspberry Pi systems.

Appears to still use host-based processing.

Host processing uses a new set of tables:

  • 2x gamma curves (8->16bpp)
  • 3D LUT (same as other models)
  • Matte data file
  • Unknown parameter table, differing only in "HDENHGAIN" value.

So it appears that some new RE work is probably warranted..

All ARM executables are _not_ stripped. WTF, but I'm not complaining! Printer uses different command language as D70 family. So it looks like a new backend is probably warranted. And a new library too, probably! Other details. Print engine is 14bpp. Matte data is 8bpp.
