Digital BW, The Print

Tyler,

Yes, IJC/OPM is completely 16 bit,  image files that are 16 bit remain 16
bit and all 8 bit files are internally converted to 16bit .  We drive the
printer with this 16bit data.

OPM uses it¹s own method to connect and print to the printer,  it completely
by-passes the Epson driver  and all  system  related printing methods.

OPM actually opens a direct handle to the printer and steams the data
directly to it.
