Color Pocket Printer Commands

Unreleased Color Pocket Printer, as mentioned in DMPJ and DMBJ.
  Packet structure identical to Pocket Printer.  Not worth reprinting here.
  Heartbeat value is 0x82, not 0x81.
  A dead print command (x = 0) must preceed actual printing instead of an empty packet instead of an empty data packet.  Probably.

Printer Commands:
1 byte
	01	Init	clears RAM buffer; reply of 00
	02	Settings
		FFFF RR GG BB
		F	flags?
			8000	???; set as a default print value
			0100	"fast mode"; set when output is half resolution (src 320x240 -> out 160x120), meaning you can print two lines per data transfer.
			0008	???; set as a default print value
			0001	???; set as a default print value
			00??	there were two more values OR'd in, but both set to zero and no reference yet
			00??
		R	red level; default 0x80
		G	green level; default 0x80
		B	blue level; default 0x80
	04	Data	sends up to 320 15bit color pixels to printer per command, little-endian (0x280 bytes)
		Little-endian, so actual order is gggrrrrr 0bbbbbgg.
		7C00	blue
		03E0	green
		001F	red
	06	Print
		cc ?? ?? ??
		c	number of lines printed.  probably prints two at a time in "fast mode"
		*other values were always set to zero
	08	Cancel
		Apparently used to reset any activities, not just printing.  Pocket Printer should also have this command.
	0F	Status	a NOP used to recieve one byte status
		00 is presumed "it's all right!"
		80	low battery
		40	currently printing
		20	???, maybe unused
		10	???, maybe unused
		08	error detected
		07	error code (0-7)
			0	feed error?  specifics unknown
			1	feed error?  specifics unknown
			2	outside operating temperature limit; specifics unknown, though one's obvious overheat and one may be too cool
			3	outside operating temperature limit; specifics unknown
			4	out of paper
			5	cover is open
			6	paper jam
			7	feed error?  specifics unknown
responds 00

  Usage is pretty much the same a Pocket Printer.  Responses are 82,xx instead of 81,xx.
  Settings (2) can be set at any time before print.  Replace the empty data packet with a "print 0 lines" packet.

Typical use:	(tentative)
	send cmd 1; response 82,00
	send cmd 2 with settings; response 82,00.
		For 320px lines (probably the default) the default is 8009808080
	send cmd 4 w/ 0x280 of graphics; response 82,??
		All formatting is done on your end, not the printer's!
	optional: send cmd F; response 82,00
	send cmd 6 w/ 0 lines; response 82,00	# this empty packet is required or the thing will not print!
	send cmd 6 w/ one or more lines; response 82,??
	send cmd F looped until response 82,00
	repeat cmds 4, 6, F until image complete
