And the ParallelPro is supposed to do color graphic dumps:

Unfortunately, there's no pixel doubling or emphasized graphics on the ParallelPro so I've stretched it out to fill the space, but you can see the color.

One thing that's a little odd is that the imagewriter has
ESC K 0 black
ESC K 1 yellow
ESC K 2 red
ESC K 3 blue
but the hexdump has K3 K3 K2 K1 I would expect it to be K0 K3 K2 K1

and if I select the Apple DMP as the printer and try color, it just omits the ESC K code to select the color.

Something is off with some of the other color printers as well. I wonder if there were some bugs with the color printing routines. It's like the color ribbon selection codes are mismatched to the type of printer.
The ESC b ESC c ESC m ESC y IBM style gets matched to a different printer.

Somehow I wonder if the color capabilities weren't exercised that much as not many people had color printers.


It took me a long time to find manuals for the okimate 20 and the IBM Color Printer (IBM 5182)

Toshiba P351C, P351SX, P321SLC manuals are nowhere to be found on the net.
