/* Mitsubish CP-D70x/CP-K60 data format
Spool file consists of two headers followed by three image planes
and an optional lamination data plane. All blocks are rounded up to
a 512-byte boundary.
All multi-byte numbers are big endian, ie MSB first.
Header 1: (Init)
1b 45 57 55 00 00 00 00 00 00 00 00 00 00 00 00
(padded by NULLs to a 512-byte boundary)
[[ D70x ]] Header 2: (Header)
1b 5a 54 01 00 00 00 00 00 00 00 00 00 00 00 00
XX XX YY YY QQ QQ ZZ ZZ SS 00 00 00 00 00 00 00
UU 00 00 00 00 00 00 00 00 TT 00 00 00 00 00 00
(padded by NULLs to a 512-byte boundary)
XX XX == columns
YY YY == rows
QQ QQ == lamination columns (equal to XX XX)
ZZ ZZ == lamination rows (YY YY + 12)
SS == SuperFine mode (00 == off, 03 == on
Lamination always turns this on!
UU == 00 == Auto, 01 == Lower Deck, 02 == Upper Deck
TT == 00 with no lamination, 02 with.
[[ K60 ]] Header 2: (Header)
1b 5a 54 00 00 00 00 00 00 00 00 00 00 00 00 00
XX XX YY YY QQ QQ ZZ ZZ SS 00 00 00 00 00 00 00

RR 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
(padded by NULLs to a 512-byte boundary)
XX XX == columns
YY YY == rows
QQ QQ == lamination columns (equal to XX XX)
ZZ ZZ == lamination rows (usually YY YY + 12)
SS == UltraFine mode (00 == off, 04 == on.. forces 8x6 print?)
UU == 01 (Lower Deck)
TT == 00 with no lamination, 02 with.
RR == 0x05 for double-cut 2x6, 0x00 for double-cut 4x6, otherwise 0x01
Data planes:
16-bit data, rounded up to 512-byte block (XX * YY * 2 bytes)
Lamination plane: (only present if QQ + ZZ are nonzero)
16-byte data, rounded up to 512-byte block (QQ * ZZ * 2 bytes)
Lamination appears to be these bytes, repeated: 28 6a ab 58 6c 22

The windows drivers seem to send the id and status queries before
and in between each of the chunks sent to the printer. There doesn't
appear to be any particular intelligence in the protocol, but it didn't
work when the raw dump was submitted as-is.
