/* Kodak 6800/6850 data format
Spool file consists of 17-byte header followed by plane-interleaved BGR data.
Native printer resolution is 1844 pixels per row, and 1240 or 2434 rows.
6850 Adds support for 5x7, with 1548 pixels per row and 2140 columns.
All fields are BIG ENDIAN unless otherwise specified.
Header:
03 1b 43 48 43 0a 00 Fixed header
II Job ID (1-255)
NN NN Number of copies in BCD form (0001->9999)
WW WW Number of columns (Fixed at 1844 on 6800)
HH HH Number of rows.
SS Print size -- 0x00 (4x6) 0x06 (8x6) 0x07 (5x7 on 6850)
LL Laminate mode -- 0x00 (off) or 0x01 (on)
UU Print mode -- 0x00 (normal) or 0x01 (4x6 on 8x6) 0x21 (2x6) 0x23 (3x6)

Note: 6800 is Shinko CHC-S1145-5A, 6850 is Shinko CHC-S1145-5B
Both are very similar to Shinko S1245!
